Cbbackupmgr restore issue from 7.2 to 7.6 with JSON unmarshall error

Couchbase Server
1

We are trying to restore data from 7.2 Couchbase server cluster to 7.6. We are getting the following error. Is there anything wrong with the restore command.

cbbackupmgr restore -a /opt/data/Couchbase/backup/DEV/FULL/20250122140039 -r APPL_DEV -c couchbase://el16189.int.corp:8091 -u bkp_admin -p bkp_admin --disable-views --disable-gsi-indexes --disable-ft-indexes --disable-ft-alias --disable-analytics --disable-eventing --force-updates --map-data Operations=APPL_DEV_Operations,APPL_DEV=APPL_DEV_NEW --include-data Operations.Log,Operations.Support,APPL_DEV.Core

Error Message: Error restoring cluster: json: cannot unmarshal number -1 into Go struct field .scopes of type uint32

Can you open a ticket with customer support?
This might be a compatibility issue with how the backup was created and how it is being restored. Tell support to look at CBSE-18435 and also direct them to this forum post.

Hi @ramesh01021988. I suspect you are using cbbackupmgr 7.2 to do the restore. cbbackupmgr is not forwards compatible. You need to use cbbackupmgr 7.6 to restore to 7.6
