Migration path
Automated migration is not possible at the moment.
Unfortunately, we cannot offer an automated migration path for Table Enhancer macros at the moment, as Atlassian is currently not providing a way to support this for Forge apps.
However, there is an open issue covering this topic, so we would appreciate votes there so that this blocker will be removed as soon as possible and we will be able to provide an automated solution.
After migrating from Confluence Server / Data Center, your old Table Enhancer macros can no longer be used. However, the original table can still be seen.
