Re: Using replication to upgrade db from 12 to 16

Hi Zashif,

I read somewhere that it was possible to have a replication on an Upgraded major version I believe by using logical replication?

Not sure myself, but was hoping there is a way as our application required some debugging after the upgrade due to improper concatenation of SQL statements that was not enforced in PGSQL-12.

Thanks

Frank

Hi Frank

Streaming/Physical Replication requires that both Master and Standby are using the same OS and same PG major version.

Thanks

Hi,

Is it possible to maintain our MASTER db in Pgsql-12 and a replica database in Pgsql-16 as SLAVE for application testing with the latest live data?

Thanks
