Miigration ok and backup ok but not up to date

Hi,
i recently update an old gitlab server v 9 to v14 with ubuntu upgrade too from v16 to 20.04

after some difficulties, i found the upgrade path and all is up to date but after backup and restore to the new server with the same version and without error, th activity and the content are not up2date on the new server.

i test sync repo between old server and new but without success, how can i check what 's the issue ?

i test with full backup, incremental without success…

is activity are include in the backup ?

regards
