Hi Atul, you could use logical replication and do an hot upgrade between the 2 servers with a zero downtime ;) If you want to use logical replication between a 9.5 , 9.6 version you could use for example pglogical. You could achieve the same result using an external logic replication tool like slony, although pglogical is more powerful. I hope that this can help you Regards, Enrico On Fri, 15 Jan 2021 18:47:51 +0530 Atul Kumar <akumar14871@xxxxxxxxx> wrote: > Hi, > > I want to upgrade my server from postgres 9.5 to 9.6, but my DB size > is in TBs and I want to do it in minimum downtime (2-3 hours) so > please help me how should I perform it. > > > Please share the document, if possible, it will be grateful. > > > > Regards, > Atul -- Enrico Pirozzi <sscotty71@xxxxxxxxx>
