A lot of the recent problems have been small bugs that occurred in configurations not tested during the beta phase. That is to say, the release itself is in no way experimental, but the testing process could use some work -- that's a discussion I would be happy to have here, but in another thread. As for upgrading -- you're contemplating a rather significant version bump, and I personally hesitate to answer because I'm not very confident that I'll be right[1]. I suspect others may be reticent for similar reasons. I think that things will go smoothly for you in an upgrade, as Amanda development remains fairly conservative in maintaining backward compatiblity. The port-range options still exist and do the same thing. I *think* that the on-disk formats and the on-the-wire network protocols are also compatible; hopefully someone will reply loudly to this email if I'm wrong about that. Probably your best bet is to just try it out in as safe a manner as you can muster.

Re: amanda upgrade questions
Upgrading amanda is always easy if you keep the same config, we always maintains compatibility. Only the new features (amrecover use security-api, auth (ssh), ...) require config change. If you use the 2.4 amrecover, no config change is needed. 2.5.2 is stable on linux, all problem seen on other OS (irix, OSF/1, solaris8, ...) are already fixed in the latest snapshot.

In config file you are referring to the .config file that is home to all the switches like --with- ssh and etc? __ Lewis [EMAIL PROTECTED] Cell: (734) 323-8776 - Original Message - From: [EMAIL PROTECTED] [EMAIL PROTECTED] To: Guy Dallaire [EMAIL PROTECTED] Cc: AMANDA users amanda-users@amanda.org Sent: Thu May 10 07:16:01 2007 Subject: Re: amanda upgrade questions Upgrading amanda is always easy if you keep the same config, we always maintains compatibility.

Re: amanda upgrade questions
Hi, It is actually quite simply to upgrade amanda. All you need to do is to download the latest version of Amanda (for this case amanda 2.5.2), untar it and execute the following commands to clean and recompile the latest build. make distclean ./configure -with-tcpportrange=5,50100 --with-udpportrange=850,859 make make install But becareful with amanda version 2.5.2 as it contains some bug issue with the amlabel on the vtapes.
