Need help in vetting my steps for Postgres DB upgrade from Ver 13.X to
ver 15.X
*ASIS-existing server = EC2 with Community PostgreSQL Ver 13.16.2*
- ensure to capture all the pre.req meant for ver 15.10 are being met.
- shutdown db.
- take offline full backup (PG_DATA folder alone) using OS command
*Proposed-new EC2 server (with new Operating System version along
Postgres Ver 15.10 Binaries)*
- install postgres 15.10 binaries
- ensure to DISABLE auto startup and shutdown of postgres 15.10
- Restore offline full backup (PG_DATA folder alone) using OS command
- start performing pg_upgrade step to upgrade postgres from ver 13.16.2
This is not going to work, you need to have Postgres 13 installed also.
