Hi all.
I have an outdated server running MySQL server from art repo.
Current installed version is mysql-5.0.83-1.el5.art

I need to go back to the "official" packages for plesk updates to work and I'm quite worried as it's a live server.

In the official centos5 server I can see these packages:

I can't find a replacement for mysql-libs package, and that's exactly the package plesk is asking to remove:

I'm not sute how should I (safely) move from art's mysql-5.0.83 to centos mysql-5.0.95

Any help? Thanks.

I may be wrong, but I think mysql 5.0 might be End Of Life:

https://www.mysql.com/support/eol-notice.html

"Per Oracle's Lifetime Support policy, MySQL 5.0 is now covered under Oracle Sustaining Support."

https://www.mysql.com/support/

"MySQL Sustaining Support - Any time, beyond the Premier Support period, available for any MySQL releases that were covered under Premier Support on or after November 1st, 2010. Support only. No new releases, no new fixes (no error correction for new issues), no new updates. Only pre-existing updates, fixes and alerts are available. Same costs as Premier Support (no extra fee)."

the language is a bit confusing, but I read that as "No fixes" for 5.0.

Yes, you are true, but I need to keep mysql 5.0 in this server, just need to update to the latest 5.0.x without upgrading to 5.5.x

The problem is not the end-of-life or support, but moving mysql from ART repo to CEntOS repo.
For example:
1) can I update from mysql-5.0.83-1.el5.art to mysql-5.0.95-1.el5_7.1?
2) can I update from mysql-server-5.0.83-1.el5.art to mysql-server-5.0.95-1.el5_7.1?
3) what happens then with mysql-libs-5.0.83-1.el5.art?

Thanks

It's EOL as far as Oracle is concerned, but Red Hat will support EL5 for a couple more years, so the packages they distribute (and thus also the ones in CentOS 5) are still supported.

You can use either the MySQL 5.0 packages from EL5 or the MySQL 5.5 packages from Atomic, both work fine with Plesk AFAIK.
