Best practices to be followed for Data center to Cloud migration

[Suvidhaa Meenachipuram Subramani]

Hi,

We are planning to migrate our Jira and Confluence data center to Cloud. Kindly guide us on the Do's and Don'ts for this migration.

If there are any best practices need to be followed to ensure a smooth transition, please let us know. 

Thanks,

Suvidhaa

Hi @Suvidhaa Meenachipuram Subramani

Absolutely — migrating both Jira and Confluence to the Cloud is a big move, but planning ahead makes all the difference.

What to do:

• Start with a health check: Clean up unused projects, spaces, and users before migration.
• Use Atlassian’s Cloud Migration Assistants: These tools help move project/space data but don’t cover everything (like apps).
• Test in a staging environment: Do a dry run before your actual cutover to catch surprises early.
• Plan for identity management: Move to Atlassian Access for SSO and user mapping early in the process.

What to avoid:

• Don’t assume apps will work the same way in Cloud—many need replacements or manual setup.
• Don’t migrate everything “as-is” if you’ve got legacy data or unused configurations. Update your field templates. Merge or split projects.
• Avoid weekend migrations without support—have a rollback plan in place.
• And finally, a big NO to down time.

OpsHub Migration Manager, an Atlassian Solutions Partner can help by:

• Migrating Jira data with full fidelity: workflows, fields, attachments, comments.
• Handling app gaps, field mismatches, and version conflicts that can derail native tools.
• Migrate without any down time i.e. Jira DC teams continue to edit data while migration is going on.

Thanks

For data transition, I'd recommend you to use this tool https://marketplace.atlassian.com/vendors/1215318/help-desk-migration 

That transfers issues much better that Jira native tool. It can do both Jira SM issues and Jira tasks. 

For the settings (like workflows, etc.) you need to be very careful when you transfer them, and do a lot of manual checks if everything transferred properly

This is the seventh time you've recommended apps from the Help Desk Migration company.

It is against the policy of this forum to promote products or services for companies without disclosing if you are an employee of that company or being paid to promote them.

Sorry, but I have to report your post to the moderators.

Just Google "What are the best practices for migrating Jira and Confluence Data Center to Cloud?" to find all the documentation that Atlassian has published that on that exact topic that explains exactly what to do.
