Обсуждение: pgpool, pgmaster and pgslave migration to ubuntu 18.04
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.

I don't know what version of Pgpool-II you are using, and trying to migrate to but if you are using Pgpool-II dedicated extensions, be sure to upgrade them as well. For more information regarding Pgpool-II version up, please refer to the release notes sections. https://pgpool.net/mediawiki/index.php/Documentation Best regards, -- Tatsuo Ishii SRA OSS, Inc.
