upgrade (svn 1.2.0) to latest apache-subversion-1.7.2

[ghostwolf59]

Hi,
Just wonder if anyone have some pointers or known issues they can share when it comes to upgrading an old svn installation (svn 1.2.0) running on a solaris 5.8 box to the latest apache version (1.7.2)

Just had a look at the svn120/bin/apr-config and apu-config where I noticed references to version 1.2.1 (even though the system path is pointing to svn120/bin)
- When issuing a svn --version it also comes up as v1.2.1 (r15230)
So it seem that the current installation is a mix between 1.2.0 and 1.2.1

Is it just a matter of installing 1.7.2 on top of the old installation or are there other issues to deal with?

Will the repository stay instact or do I need to export/import existing source code into the new installation?

On the client side we are currently using TortoiseSVN-1.6.16 as well as subversion client 1.6.16
Would then need to be upgraded or ...?

Also wonder if existing hook scripts & user configurations for repositories would need to change as part of this upgrade

cheers
