Which Channels now?

Ok, I've successfully upgraded from 7.5.4 to 8.1 on RHEL3.

I've been using primarily YUM for my updates with an occasional hit on up2date.

I've added yum psa-8.1 http://www.atomicorp.com/channels/plesk ... hat/3/i386 to my source file and have commented out
# [psa-7.5]
# name=Atomic Rocket Turtle - $releasever - SW-Soft PSA 7.5 RPMS
# baseurl=http://3es.atomicrocketturtle.com/atomi ... eleasever/

from my yum.conf.

So, just trying to be sure all my bases are covered so I can make sure I've got the latest updates can I add the centos channel for 8.1? or no?

And the next move would be to go from RHEL3 to RHEL4 or Centos4 and what is the best way to move to that? Backup all and have a restore done on the drive with RHEL4 and PSA8.1 and then copy all back from a slaved drive?

Thanks.

I did something new with the atomicorp.com PSA archives, thats using the psa updater to mirror the contents into the yum archive. That works really well, unfortunately for some reason it doesnt download the third-party packages. So it looks like Ive got to go in and manually resolve that. This arouses my discontent.

For migrations, I favor using 2 servers with the migration manager. You can run both systems at the same time for testing purposes, and with some DNS trickery never experience any downtime.

Scott, found this in a different thread.. This still hold true?

Scott wrote:yeah, you can use the version from CentOS3, as well as use all of CentOS 3's yum channels. If you update it through yum long enough, eventually the box will become CentOS3, so it kind of begs the question... why even buy 3ES if you're eventually going to turn it into a CentOS3 box

Yep, it will eventually update enough stuff that you're running a defacto CentOS3 box. Functionally of course, this means nothing. The only thing Ive ever seen it effect was up2date, because it cant figure out what distribution it is any more.

Ok, so I update with the CentOS channel for 3 at some point I can do an inplace upgrade to 4? or is this bad reasoning? So I should just do a PSA backup to a spare and have a reimage done with Centos4 or RHEL4 yes?

You can upgrade from 3 to 4, its just a big change thats all. It can kind of get messy, which is why I normally do re-installs.
