Currently we are using confluence-server software and now we are in process to upgrade server license to Data Center in Cluster-node. Below startup steps has been completed and stuck on last step.
1) Data Center software installation is completed and started server.
2) Choose Your deployment section completed
3) Data Base setup step has been completed and DB connected as expected.
4) Now we have struck on "Load Content" option. Planning to use "Restore From Backup" option.
We have stuck on the last step because we are not sure how to take the backup of all the space from existing confluence single server to import Data Center server. We have more 100 spaces and very difficult to the backup of each space and import to Data Center.
Could you please advice if we have any simple way to migrate all the spaces from confluence single server to confluence Data Center.
