Hi Dan, (and Matt from Gloucester Research)

thanks for the feedback. I had formed the impression that we'd need to
keep the master and slaves in sync as regards major versions but maybe
not.

Just to cement your viewpoint in place though, the only other posting
I have seen, Matt's, seemed to be in reply to yours which makes
your "As one other poster said" a little tautological!

The central IT guys here, for whom my Comp Sci school IT folk administer
the Condor grid, were supposed to be giving me the resources to try out
a newer Condor, in isolation from the existing pool, next week, just in
time for Xmas - it's like being a kid again!

I would have been looking to start afresh from the 7.4 series.

If you tell me categorically that I can upgrade the master to a later
version and not affect the existing grid then that'd enable VUW to
take a huge step in the right direction at a much quicker pace.

Thanks again for the feedback,
Kevin
