[rt-users] RT 3.8.10 and 4.0.1 in apache vritual hosts - possible?

[Yan Seiner]

I've been struggling to get two instances of RT running on the same
server.  One is our current 3.8.10 and the other is a proposed migration
to 4.0.1.

I am installing from source.

I'm finding that since FastCGI in apache is configured at the server level
and not at the virtual host level, and 3.8 and 4.0 use different fastCGI
handlers, I can get one running and not the other.

I have the databases, paths, etc. straight.  I can enable one or the other
but not both; one always crashes with 500 - internal server error.

Does anyone have any hints on how to make this work?  Or is it just
impossible?
