4.4.1 upgrade issue - no SSVM, CPVM, Router

[Noel Kendall]

I recently attempted an upgrade from 4.2.0 to 4.4.1 and in the process, 
mytemplates were not properly updated. I have the templates now,but SSVM and 
CPVM are gone.Have been looking through the source to see under what 
conditions,and where/how the SSVM is created once gone.I would appreciate a 
hint from someone who knows their way aroundthe source to help me narrow down 
where to look.Many thanks,Noel
