Hi,
I'm exploring the options to migrate postgresql master, slave along with pgpool from ubuntu14.04 to 18.04. Please help me understand the following.
1. What are the available options for migrating from one version of O/S to the other (Here ubuntu 14.04 to 18.04) ?
2. Document references.
3. Any best practices.
4. I'm assuming that migrating pgpool and pgmaster,slave can be done separately and there isn't any dependency between them. (I mean first I can separately migrate pgpool and then later migrate pgmaster/slave) is that correct?
Regards,
Venkatesh.
