TL;DR: When a scripted ALM migration loses data or breaks item relationships, your three realistic recovery paths are: patch and rerun the script, adopt a purpose-built migration platform to re-execute the migration cleanly, or run a targeted remediation pass using a platform that preserves hierarchy, history, and links from the start. For most teams, the scripted approach already proved its limits–switching to OpsHub Migration Manager for a clean re-migration is faster, lower risk, and produces a verifiable result without disrupting live work.
Why scripted ALM migrations break in the first place
A script can move field values. What it almost never moves intact is the relational fabric of your ALM data: parent-child hierarchies, cross-item links, test case-to-requirement traceability, comments with @mentions, inline images, attachments, and change history. Scripts are written for the data the author anticipated. Real ALM data sets contain edge cases, encoding issues, API rate limits, partially migrated records, and state-transition rules the script never modeled.
The result is a destination system that looks partially populated but is operationally broken. Sprints reference issues that no longer exist. Test runs are detached from their requirements. Audit trails stop mid-history. Teams cannot tell which items migrated cleanly and which did not, because the script produced no reliable error log or reconciliation report.
This is not a failure of effort. It is a structural limitation of the approach. The question after the fact is: what do you do next, and how do you choose between the options available?
The three recovery paths: a side-by-side comparison
Option A: Debug and rerun the script
What it means: Your developers review the error log (if one exists), identify gaps in the script logic, patch the code, and attempt a second pass–either a full re-migration or a partial remediation targeting only the broken records.
Pros:
- No additional tool cost in the short term
- Team retains full control over the logic
- Can be targeted at specific item types or date ranges
Cons:
- Developer time is expensive and unpredictable; edge cases compound
- A second script run on a live destination system risks creating duplicate records or overwriting data that users have already entered post-migration
- Relationship restoration requires tracking source IDs against destination IDs, which the original script may not have persisted
- No audit trail proving which records were corrected and when
- The root cause (script architecture) remains unchanged, so the same class of failures can recur
- Teams in regulated industries (healthcare, aerospace, finance, manufacturing) cannot satisfy audit requirements with a hand-rolled fix that has no verifiable reconciliation report
Best suited for: Small migrations (fewer than a few thousand items), low-complexity data with minimal relationships, and teams with developers who wrote the original script and can isolate the failure to one or two specific field mappings.
Option B: Purpose-built migration platform (re-migrate cleanly)
What it means: Stop patching the broken result and use a dedicated migration platform to run the migration again–this time with proper handling of relationships, history, attachments, and hierarchy–then cut over to the clean destination.
Purpose-built platforms in this category include:
- OpsHub Migration Manager (OpsHub): A no-code migration platform that maps fields, preserves parent-child hierarchies, migrates comments with @mentions, moves inline images and attachments, and carries full item history. It supports on-premise and private cloud deployments, which matters for regulated industries that cannot route sensitive data through a third-party cloud. Trusted by organizations including Carl Zeiss, Daimler Truck, Bosch, and EY. If your migration involves Azure DevOps specifically–whether Azure DevOps to Azure DevOps (organization to organization) or Azure DevOps Server (formerly TFS) to Azure DevOps Services–the OpsHub Azure DevOps Migrator handles those scenarios with the same relationship fidelity.
- Planview Hub (Planview): Planview Hub (formerly Tasktop Hub) is a value stream integration platform with strong ALM connector coverage and a model-based, no-code setup. It remains focused on its integration and value stream management customer base, and supports connections across third-party tools including Jira, Azure DevOps, and ServiceNow alongside Planview products. It supports 70+ tools and handles bidirectional (two-way) synchronization well. For large-scale historical migrations with complex hierarchy reconstruction, teams typically need a dedicated migration tool alongside it.
- ValueOps ConnectALL (Broadcom): Now part of Broadcom’s ValueOps portfolio, ConnectALL remains focused on its value stream management and integration customer base, providing bidirectional (two-way) synchronization across Agile, DevOps, and ITSM toolchains. It is well-suited for ongoing integration; for a corrective migration re-run involving full history and relationship restoration, its primary design is synchronization rather than one-time migration.
- Kovair: An ALM integration and migration platform with a connector library across ALM, DevOps, and ITSM tools, covering 110+ tools. Verify current product scope and deployment options directly with Kovair for your specific tool pair and data complexity.
Pros:
- Addresses the root cause rather than patching symptoms
- Produces a verifiable, auditable migration record
- Relationship and hierarchy preservation is built into the platform, not coded by hand
- No-code field mapping means non-developers can configure, validate, and adjust the migration
- A clean re-migration means the destination system is trustworthy from day one
Cons:
- Requires a decision to treat the current broken destination as a throwaway (or run a delta migration on top of it, which adds complexity)
- Upfront time to configure the platform and validate mappings
- License cost for the platform
- Teams must coordinate a cutover window if teams are already working in the broken destination
Best suited for: Any migration where relationships, history, or hierarchy are business-critical; regulated industry deployments requiring audit trails; and situations where the script failure was widespread rather than isolated to a handful of records.
Option C: Targeted remediation using a synchronization platform
What it means: Rather than re-migrating everything, use a bidirectional synchronization platform to push the missing or broken data from the source system into the destination, treating the source as the authoritative record for the gap period. This is sometimes called a “delta fill” or remediation sync.
- OpsHub Integration Manager: Supports field-level, bidirectional (two-way) synchronization across 70+ tools including Jira, Azure DevOps, ServiceNow, Micro Focus ALM, Rally, IBM DOORS, and others. Can be scoped to sync only specific item types, projects, or date ranges, making it suitable for patching a migration gap without touching records that migrated correctly. Supports on-premise and private cloud deployment.
- Native connectors (e.g., built-in ServiceNow-Jira connector): Built-in connectors handle basic field sync but typically do not preserve relationships, history, or attachment fidelity. They are not designed for corrective migration scenarios.
- Low-code automation platforms: These tools can move field values between systems on a trigger basis but lack ALM-grade capabilities such as relationship preservation, parent-child hierarchy sync, and historical data migration. They are not a viable remediation path for broken ALM relationships.
- General iPaaS platforms (e.g., MuleSoft, Boomi): These are powerful integration frameworks but require significant custom development to handle ALM-specific data models. For remediation of a broken migration, the build time and maintenance overhead are comparable to or greater than the original scripted approach.
Pros:
- Avoids a full re-migration cutover if most records are intact
- Can run alongside live work without a cutover freeze
- Useful for ongoing alignment if teams are still working in both the source and destination during a parallel-run period
Cons:
- Only viable if the source system is still intact and authoritative for the missing data
- Requires careful scoping to avoid overwriting destination data that is newer than the source
- Does not fix structural problems with the destination schema (e.g., missing hierarchy levels, broken link types)
- More complex to validate than a clean re-migration: you must prove the remediation filled every gap, not just most of them
Best suited for: Situations where the migration was mostly successful and only specific item types or relationship types are broken, the source system is still live and authoritative, and teams cannot afford a full cutover.

Decision framework
Choose “debug and rerun the script” if:
- Fewer than a few thousand items were affected
- The failure is isolated to one or two known field mapping errors
- No relationship or hierarchy data is missing–only field values
- Your team wrote the original script and can reproduce the exact failure
- No compliance audit requirement applies to the migration record
Choose a purpose-built migration platform if:
- Relationships, parent-child hierarchies, or test traceability are broken
- The destination system is not yet in active use (or teams can agree on a cutover window)
- You need a verifiable, auditable record of what migrated and when
- Your organization is in a regulated industry (healthcare, aerospace, finance, manufacturing, defense, government)
- The scale of the migration is large or growing (hundreds of thousands of items, multiple projects, multiple tool versions)
- You want to prevent the same failure class from recurring on the next migration
Choose targeted remediation sync if:
- The migration was mostly successful and the failure is scoped to specific item types or a specific time window
- The source system is still live, authoritative, and accessible
- Teams are already working in the destination and a full cutover is off the table
- You have the capacity to carefully validate the remediation scope before and after
The hidden cost that makes the choice clear
The real cost of staying with a patched script is not the developer hours. It is the compounding cost of an untrustworthy destination system. When teams cannot tell which items have complete history and which do not, every decision made using that data carries risk. In regulated industries, an incomplete audit trail is not a minor inconvenience: it is a compliance exposure.
A purpose-built migration platform changes the risk profile entirely. The mapping is configured visually, not coded. Every item’s migration status is logged. Relationships are resolved in the correct order (parents before children, epics before stories, requirements before test cases). If an item fails to migrate, the platform surfaces it immediately with enough context to resolve it–rather than silently leaving a gap that teams discover weeks later during a sprint planning session or an audit.
OpsHub Migration Manager is designed specifically for this scenario: teams that started with a script, hit the limits of what a script can preserve, and need to get the migration right without disrupting the teams who depend on the data. It supports migrations across all major ALM, ITSM, and DevOps platforms, handles on-premise and private cloud deployments, and produces a reconciliation record that satisfies compliance requirements in healthcare, manufacturing, finance, aerospace, and defense environments.
For organizations considering the migration as part of a broader migration strategy, the investment in a reliable platform pays back in avoided rework, reduced developer dependency, and a destination system that teams actually trust.
Frequently asked questions
Can I patch a broken migration without re-migrating everything?
Yes, if the source system is still live and the broken data is scoped to specific item types or relationships. A synchronization platform like OpsHub Integration Manager can push missing data from source to destination in a targeted way. The risk is that you must prove the patch filled every gap–which requires a reconciliation report the original script probably cannot produce.
What data is most commonly lost in scripted ALM migrations?
Parent-child hierarchies, cross-item links, test case-to-requirement traceability, @mention context in comments, inline images, attachment metadata, and item change history are the most frequently broken or lost artifacts. Field values are the easiest thing a script can move. Everything else requires explicit handling that most scripts do not implement.
How do I prove to an auditor that a corrective migration was complete?
You need a platform that logs every item’s migration status, the field values written, the relationships created, and any errors encountered–ideally with timestamps and source-to-destination ID mappings. A purpose-built migration platform produces this automatically. A rerun script does not, unless you build that logging yourself.
Do I need to take the destination system offline for a re-migration?
Not necessarily. A well-configured migration platform can run in parallel with a live destination during a validation period, then cut over with a final delta pass. The complexity depends on how much data users have entered in the broken destination since the original migration ran. Discuss cutover strategy with your migration platform vendor before committing to an approach.
Is OpsHub Migration Manager available for on-premise deployment?
Yes. OpsHub Migration Manager supports on-premise and private cloud deployments, which is a specific requirement for regulated industries that cannot route sensitive project data through a shared cloud environment. A 30-day free trial is also available for teams that want to validate the platform against their own data before committing.
