Folks, We've been running 2.4.x (presently 2.4.4p1) on Solaris 9 since 2002 (and earlier versions back to about 1997 ..). The 2.4.4 release has been enormously successful, and has saved our tail feathers any number of times. Clients are Solaris and Linux of various vintages (including some Fedora that should be retired.)
We're bringing up ZFS file systems; looks like it's time to move to 2.6.1. I've read the UPGRADING file in the distribution, and am seeking guidance on some finer points. We keep daily backups for 4 weeks, weeklies for 4 months, and monthlies for 1 year. Can I expect that 2.6.1 amanda will be able to 'amadmin find' and recover tapes written by 2.4.4? (My guess is 'yes'.) Is there compelling merit to doing an upgrade to 2.5.1 as a tranisitional step? (Guess = no). Updating all of the clients in one fell swoop would present challenges. A number of client machines (but not all) are presently running 2.5.1, the result of a prior but incomplete attempt to upgrade. The 2.5.1 clients work fine with the 2.4.4 server. Can I expect the older clients to work with a 2.6.1 server? (Guess = I hope so.) Or should I upgrade the clients first and the server second? (Guess = no.) My guesses are just that, and have no basis. Some guidance (even if only more informed guesses) would be appreciated. Thank you. Bryan
