A technical roadmap has been published on the CapitaES site.
SQL2005 migration will be available in August 07.
All updates from August 07 on will only run on SQL 2005 / Express
SQL 2005 will need .net 2 framework
Support for Win2000 Pro is being dropped Feb 2008
And of course Office 2003 is now needed for SIMS
Plus the version of Veritas I have doesn't backup SQL 2005 either.
Lucks like I'll be busy in the summer again :-)
