[WBEL-users] Migration to WBL 3 from Redhat

[Tom Cooper]

I recently migrated a couple of RH boxes to WBL 3.  I've had some good 
experiences with this.

I basically followed the process in a handy whitepaper on the IBM site 
documented here:
http://www-1.ibm.com/servers/eserver/iseries/linux/pdfs/rhel3_upgrade.pdf

I did an upgrade in place without reformatting the filesystems, and one 
thing that I've noticed is that there are rpm's in the rpm db that were 
for the redhat installation.  If you're planning an upgrade-in-place, 
I'd recommend removing/renaming the rpm database directory prior to 
installation of wbl on that filesystem.  If you don't, I've had good 
experience with rpm -e on the old versions.  So far I haven't trashed my 
box.

Hope folks find this helpful.

Tom Cooper
