Hmm, I'm sure I've seen some messages recently about AIX ~ have you searched the list archive
(see http://subversion.apache.org/mailing-lists.html for search links)?

Did you have a look at the Subversion Book contents linked from that FAQ?  Useful reading.

That should be good for you, I've done similar on Windoze.

> Can you also elaborate step 7 on hook scripts and etc.,?

Subversion supports "hook scripts" that are called by subversion before/after specific actions
[2].  They are in the repositories `hooks` folder (along with a load of templates with the
`.tmpl` extension).  If you have any hooks active, e.g. for emailing people after a commit,
then you need to transfer these to the new repository yourself, there is no automatic support
for this.  Make sure that you set the required permissions on these files for whichever user
account runs the subversion server process!

Hope that helps.  Do read the release notes for each version upgrade before you do anything
and don't do it on a live system without testing offline!
