Maintenance issues

[Pagurek,Debbie [NCR]]

Sorry for cross-posting but I have some questions relevant to both the
mapserver and chamelon lists. There's a server at my workplace that is
running php 3.3, Mapserver 4.4, and an older csv version of chameleon
(looks like april 2004 which is way before the 2.2 release). There are
existing applications on the server that shouldn't break, but few people
around who can maintain them.

I know that I could put mapserver 4.6 and chameleon 2.2 on this server
at the same time as the older versions, but am I correct in thinking
that the php 3.3 version won't work with these up to date versions? And
I can't put a second version of PHP on the server, correct? If we
upgrade the php version to 3.11, what is the likely impact on the old
mapserver and chamelon (and mapserver/mapscript) applications?

I'd appreciate any comments that people have on the regular mainenance
planning for their projects. 

Thanks,
D. Pagurek
