Hi, Im new in this list and I have recently started a project to migrate all our servers from RHEL to Centos. My question is if anyone have any tips/tricks regarding online migration from RHEL to Centos, especially between ver. 5? I have read most stuff I have found thru Google and the Centos wiki and most migrations have worked fine except the RHEL 5 - Centos 5 migration. Hit a few bumps and lost the rpm db and such... Any tips/pointers/tricks/experiences are welcome. Yes, I know a clean reinstall is the best thing to do. Cheers
