we have tried to delete all fndx_Sync_VersionNumber indexes and try to update again facing same issue.
 
Kindly advise me for this issue also suggest what kind of order  we must install Cumulative updates 9.1
Either we need install one by one or we can directly install update 9.1.20.11 on top of D365 9.0.51.6 version.
 
kindly need you suggestion on the same
