Your migration hasn’t started yet. Start syncing now so cutover day is smaller, faster, and lower risk.
Atlassian’s Confluence Cloud Migration Assistant (CCMA) moves your content. But the size of the job it has to do — and the risk of something going wrong — depends heavily on how far apart your Data Center and Cloud environments are when you run it.
Most organizations start their migration with a large, messy initial transfer, then spend time cleaning up the gaps. There’s a better sequence: stand up Space Sync for Confluence before you run CCMA, start syncing content early, and let the delta shrink before the cutover begins.
The result is a smaller, faster, lower-risk migration when you’re ready to pull the trigger.
What this looks like in practice
Your Confluence Cloud instance is provisioned and your migration is scheduled for Q3. It’s currently Q1. Your team has two quarters of active Data Center usage ahead before the cutover — two quarters during which your Data Center content will continue to change, grow, and diverge from the Cloud environment that’s sitting empty.
When Q3 arrives, CMA will have a large, moving target to migrate. Any content that changed after the initial assessment will need to be reconciled manually. Your migration window will be longer, and your confidence in the cutover will be lower.
Instead: deploy Space Sync for Confluence now. Begin syncing your most critical spaces to Cloud immediately. By the time Q3 arrives, Cloud already reflects your current Data Center content. CCMA runs a much smaller transfer. Your team validates against a Cloud environment that looks familiar, not one that reflects a months-old snapshot.
What breaks without early sync
- CCMA migrates a point-in-time snapshot; everything that changed after the assessment is a gap the team has to close manually
- Migration windows are longer because there’s more content to reconcile at cutover
- Cloud validation is slower because teams are comparing against an outdated state they don’t recognize
- Errors or mismatches found during validation delay the cutover, increasing cost and stakeholder pressure
- The longer the gap between assessment and cutover, the larger the delta — and the higher the risk
How Space Sync for Confluence fixes this
Space Sync for Confluence establishes a live sync between your Data Center and Cloud instances before migration begins, giving your team a continuously updated Cloud environment to work against.
Start with your highest-priority spaces — the documentation your teams need most and that changes most frequently. Space Sync for Confluence keeps those spaces current in Cloud throughout the pre-migration period. When CCMA runs, it handles less. When your teams validate, they’re reviewing content that looks like what they use every day, not a months-old export.
After CCMA completes the main transfer, Space Sync for Confluence continues to run for any content that changed during the migration window itself, filling the gap that CCMA’s point-in-time approach leaves behind.
Key capabilities for this scenario:
- Start syncing priority spaces to Cloud before migration begins
- Continuous sync throughout the pre-migration period keeps the delta small
- Bulk sync for alignment checkpoints before and after CCMA runs
- Complements CCMA — fills the gap between the initial snapshot and cutover day
- Sync scope controls to define which spaces sync in which phase
What changes for your team
Your migration window is shorter because there’s less to reconcile on cutover day. Your Cloud environment looks like a live system, not a historical snapshot. Validation is faster because teams recognize the content they’re reviewing. Confidence in the cutover is higher because you’ve been running and validating the sync for months, not hours.
Pre-migration sync turns the cutover from an event your team has to survive into a step they’ve already mostly completed.
Built for the people planning the migration
Cloud Migration Lead / Transformation PM — You’re accountable for the migration timeline and cutover quality. Starting sync early reduces the risk surface on cutover day and gives you more control over the schedule.
Confluence Administrator — You’ll be the one reconciling content gaps if the delta is large. Space Sync for Confluence reduces that workload before it starts.
IT Manager / Atlassian Platform Owner — A longer migration window means more operational risk. Starting sync early shrinks the window and keeps both environments stable throughout.
“Confluence Cloud Migration Assistant migrates a snapshot. Space Sync for Confluence makes sure that snapshot is as current as possible — and stays that way.”
Space Sync for Confluence works alongside Atlassian’s Confluence Cloud Migration Assistant, not as an alternative to it. Use both together for a migration with less rework and a cleaner final cutover.
