Step 1, undo what has been done and never use a force or nodeps!

Step 2, upgrade up2date to centos 3 (more on this when I find our notes)

Step 3, update all packages which are not customized.

Step 4, baby steps on customized configs/packages. ( you will need a lot of
compat rpms to work with.)

Step 5, get upgraded to 4, then 5

We have upgraded all of out 7.x and 9 systems to centos 4. Except one, it
has sendmail, apache, etc incompatibilities.
