I need to mantain (bring back to life, in fact) a system based on xampp 1.5.1. Basically I need to add subversion support to apache server. I've been trying with current mod_dav_svn.so modules but Apache refuses to load them - it seems to me that each apache version needs a specific mod_dav_svn.so module. Since xampp didn't include mod_dav_svn module until 1.6.0 I decided to start upgrading xampp. From 1.5.1 to 1.5.2 was easy: there is a specific installer/upgrade. Problem appears from 1.5.2 to 1.5.3: there is no such upgrade.
Since it is explained that xampp does not write the windows registry I tried to install directly 1.7.3 (current xampp version) and move manually database files and htdocs; but then mysql server doesn't start (at least mysqladmin complains about the change).
How could I proceed to continue upgrading from 1.5.2? What about a way to obtain mod_dav_svn.so version that is needed in xampp 1.5.2?
