Upgrade from 1.0.x to 1.2.x?

Rancher 1.x
#1

Has anybody attempted to upgrade to 1.2.x from an old version? I am using a single server (non HA) with a local MySQL database.

I am starting to plan the move from an old version to the new and am wondering what sorts of caveats and issues there might be. Are there any guides or advice to follow?

This is not a situation we’ve tested… While I don’t know of any reason that straight to 1.2 wouldn’t work, I would suggest:

  1. Backup the current DB (docker exec <rancher/server container id> mysqldump -A > 1.0.x.sql)
  2. Upgrade to 1.1.4 (use v1.1.4 instead of latest).
  3. Check that everything is ok.
  4. Backup the current DB again (docker exec <rancher/server container id> mysqldump -A > 1.1.4.sql)
  5. Upgrade to 1.2.

Thanks @vincent, I’ll try it. Do I need to do anything with my old load balancers or is that all taken care with the upgrades?
