The Append mode has been removed because we reorganised the backends to support different embedded key-value stores and not all stores could support append.
Beside, doing an import append does break replication and requires to fully re-initialize all replicas.
You should use ldapmodify -a to add new records. If it’s not fast enough, you should split the input file in multiple subsets and add all subsets in parallel.
But “ldapmodify -a” doesnot work on attributes where NO-USER-MODIFICATION is defined in schema(like createTimestamp, modifiersName ….)
In our product while upgrading, we need to preserve existing node and add a new node as well(which was done by append).
Do we have any ldif merge kind of mechanism, by which we can simulate append?
