Hello,
one idea might be the following:
Example:
ASE Linux needs to be migrated to ASE AIX.
First setup MSA replication from ASE Linux to ASE AIX, use the dump marker for the subscription.
The replication won't start until you run a dump database.
Setup a second ASE Linux, where we will do the XPDL commands.
Now dump the database on your production ASE Linux, the dump marker will be given to RS and all changes not captured with this dump will be moved into the inbound / outbound queue. Since the DSI is down, nothing is replicated.
Now load this dump into your second ASE Linux and do your XPDL commands (as described in the manuals). When this is done, dump this database and load it into your ASE AIX and bring it online.
And finally resume your DSI connection again.
The disadvantage is that the outbound queue in the RS needs more space to keep all the transactions and it might take some time before the systems are in sync.
You should test this with a small database so you are familar with the procedure.
Hope this will help.
Best regards,
Stefan
