How to Manage Shared Confluence Spaces Across Cloud and Data Center

During a hybrid Confluence migration, shared spaces often become the hardest to manage. Teams continue collaborating across Confluence Cloud and Confluence Data Center, but updates, comments, and attachments quickly fall out of sync. Without a clear approach, shared spaces turn into a source of confusion rather than collaboration.

This guide explains how teams can manage shared Confluence spaces across Cloud and Data Center during a hybrid migration, while keeping collaboration effective and reducing manual coordination.

When this approach is needed

This approach is especially useful when:

• Teams are actively collaborating in both Confluence Cloud and Data Center

• Shared spaces exist in both environments

• Teams depend on the same documentation to plan work or make decisions

• Admins are frequently asked where updates should be made

If your migration involves a full cutover with no overlap, shared space management is much simpler and may not require this level of coordination.

Why shared spaces become difficult during hybrid migration

In a hybrid setup, collaboration naturally splits. One team updates a page in Cloud, another adds information to the same page in Data Center. Comments and attachments live in different places, and teams lose visibility into each other’s work.

Atlassian’s Confluence Cloud Migration Assistant helps move spaces, but it does not support collaboration across environments once migration begins. Without an explicit strategy, shared spaces become fragmented and harder to maintain over time.

Step 1: Identify which spaces are truly shared

The first step is to determine which spaces actually require cross-environment collaboration.

Focus on spaces that:

• Are used by multiple teams or departments

• Support ongoing projects or programs

• Contain reference material that must stay current

Not every space needs to be shared during migration. Being selective reduces complexity and makes collaboration easier to manage.

Step 2: Define how teams should collaborate during the hybrid phase

Before introducing any technical solution, align on expectations.

For each shared space, clarify:

• Which teams are actively contributing content

• Whether updates are expected from both environments

• How teams should treat synchronized content

Clear guidance reduces conflicting edits and supports smoother collaboration.

Step 3: Maintain alignment across Cloud and Data Center

As hybrid collaboration continues, manual coordination becomes difficult to sustain. Teams often look for a way to keep shared spaces aligned automatically, without forcing everyone into the same environment.

Space Sync for Confluence Data Center is commonly used to synchronize selected shared spaces between Cloud and Data Center. Rather than syncing everything, admins focus on collaboration-critical spaces where consistency matters most.

An initial sync establishes a clean baseline so both environments start aligned.

Step 4: Validate shared space consistency

After synchronization is in place, validate that shared spaces are behaving as expected.

Admins typically:

• Review a small set of pages in both environments

• Confirm that content, structure, and attachments match

• Ensure teams can continue collaborating without confusion

This step helps build confidence before relying on synchronized spaces day to day.

Step 5: Adjust shared space scope as migration progresses

Hybrid migration is not static. As teams move fully to Cloud, some spaces no longer need to remain shared, while others become more important.

To keep collaboration effective:

• Review shared spaces periodically

• Remove spaces from synchronization when they are no longer needed

• Communicate clearly to teams as collaboration patterns change

This keeps shared space management aligned with migration progress.

Common pitfalls to avoid

A few patterns often create challenges during hybrid collaboration:

• Treating all spaces as shared by default

• Syncing spaces without clear ownership

• Relying solely on process and communication for extended periods

Intentional scope and clear expectations help prevent collaboration breakdowns.

How this supports effective collaboration

Managing shared Confluence spaces intentionally allows teams to collaborate across Cloud and Data Center without constant coordination overhead. Teams maintain visibility into shared work, admins spend less time resolving confusion, and collaboration continues uninterrupted during migration.

Most importantly, this approach supports ongoing work while migration progresses, rather than forcing teams to wait for a full cutover.

Support collaboration across Confluence Cloud and Data Center

Use Space Sync for Confluence (Data Center) to keep shared Confluence spaces aligned while teams collaborate across environments during hybrid migration.
