How to maintain data integrity during Jira Cloud migrations

This guide explains how to maintain data integrity during Jira Cloud migrations, and Jira migration in general, using Jira Cloud Migration Assistant (JCMA) with OpsHub Migration Manager (OMM). It covers what moves, where integrity breaks, the checks that keep data accurate, and how the two tools work together.

How to maintain data integrity during Jira Cloud migrations

TL;DR

A Jira Data Center to Cloud migration puts issue history, attachments, links, workflows and user identities at risk when data is moved without validation. Jira Cloud Migration Assistant (JCMA) handles the core migration, but it needs downtime, and updates made in that window can be lost. OpsHub Migration Manager (OMM) adds parallel operation, reverse sync, data transformation and reconciliation to protect data integrity.

What is a Jira Data Center to Cloud migration?

A Jira Data Center to Cloud migration moves your projects and configuration from a self-hosted Jira Data Center instance to an Atlassian-hosted Jira Cloud site. Teams usually move to reduce infrastructure upkeep and to reach features that are available only in Jira Cloud.

A full migration has to carry more than issues. The data that must arrive intact includes:

Projects, issues, subtasks and full issue history
Comments, attachments, issue links and timestamps
Users and groups, plus their roles and permissions
Workflows, custom fields, screens and schemes
App and add-on data, where a Cloud version supports it

How to maintain data integrity during Jira migrations?

To maintain data integrity during Jira Cloud migrations, validate the source before you move, preserve every record with its context, and reconcile the target against the source after the move. The practices below apply to any Jira migration.

Run a pre-migration integrity check on the Data Center source and fix errors before you start. Clean up stale projects, fields and users so less can go wrong.
Map user identities from Data Center usernames to Cloud Atlassian Account IDs so history, comments and assignments stay with the right people.
Run a test migration to a sandbox Cloud site first. Check history, attachments, links, workflows and permissions before the live run.
Preserve full context. Issue history, comments, attachments, links, timestamps and audit trails should move together, not as stripped records.
Transform fields, workflows and schemes into a Cloud-ready structure before cutover, so data maps to the right place instead of being dropped.
Reconcile source and target. Compare record counts and relationships, report mismatches, and retry failed records rather than assuming success.
Keep the Data Center source read-accessible as a fallback until validation is complete, so nothing is lost if a check fails.

How do JCMA and OpsHub Migration Manager work together?

JCMA runs the core, structured migration, and OpsHub Migration Manager (OMM) adds the controls that keep data accurate across a phased move. OMM extends JCMA; it does not replace it.

JCMA moves projects, issues, workflows, custom fields, schemas and metadata. OpsHub Migration Manager (OMM) adds parallel operation, reverse sync, delta sync, data transformation, consolidation and reconciliation so Jira Data Center and Jira Cloud can run side by side until you choose to cut over.

What does a safe phased Jira migration look like?

A safe Jira migration moves in phases rather than a single freeze. JCMA handles the first structured pass of projects, workflows, fields and schemas. OMM then syncs ongoing changes and manages what needs adaptation, such as field mismatches or data-level transformation.

Because Jira Data Center stays live and reverse sync keeps both systems aligned, teams can keep working while projects move in the background. You validate each phase, confirm the records match, and control when cutover happens. OpsHub has worked in migration and integration for over two decades and supports 70+ tools, so add-on and cross-tool data can move with its context.

Frequently asked questions

How do you maintain data integrity during a Jira migration?

You maintain data integrity by validating the source before the move and reconciling the target after it. Run an integrity check and clean up the Data Center source, map user identities, migrate to a sandbox first, and move issue history, attachments, links and timestamps together. After the move, reconcile source and target, retry failed records, and keep the source accessible as a fallback until checks pass.

What is the difference between JCMA and OpsHub Migration Manager (OMM)?

JCMA is Atlassian’s native tool for migrating Jira projects, workflows, users and issue data. OpsHub Migration Manager (OMM) adds parallel operation, reverse sync, delta sync, data transformation, consolidation and reconciliation on top of that core migration. OMM extends JCMA; it does not replace it.

Can you migrate from Jira Data Center to Cloud without downtime?

Yes. With JCMA and OMM together, Jira Data Center stays live while data moves in the background. OMM reverse sync keeps both systems aligned, so teams keep working and you control the cutover timing instead of freezing the instance.

Does a Jira Cloud migration move app and add-on data?

Not automatically. An app may exist on Jira Cloud without its data moving across. Assess every app early, decide which are needed on Cloud, and confirm whether each supports data migration before you plan cutover.

Can selected Jira projects be migrated instead of everything at once?

Yes. OMM supports selective and phased migrations by projects, teams, issue types, statuses, date ranges or custom criteria. This lets you move in controlled waves and validate each one before the next.

What happens to users and permissions during a Jira migration?

Users are matched from Data Center usernames to Jira Cloud Atlassian Account IDs, which are linked to email. Run the user assessment early so accounts, roles and permissions map correctly and history stays attached to the right people.
