New datastore is in and appears to have calmed things down. Now, is there a
way to move my printer name mappings from the old farm?

I've actually still got a PS4 server in the farm but it's on the point of
hardware death and about to be replaced with a PS3 equivalent. It has to be
powered down daily.
First thing in the morning I'm building a new farm / datastore and migrating
the servers across to it. I don't suppose it's possible to migrate farms
without upsetting the sessions already running on each server is it. I know,
I want the moon on a stick etc etc.
Thanks for the pointers gents.

Ah, I understand what you're saying there - top tip.
But, my (badly phrased) point was that if you upgrade your DS (to PS4) you
can't go to a situation (like Angus appears to have) where you have *no* PS4
boxes at all.

I'm not sure what your saying there.
Your DS will be automatically upgraded once a PS4 box is introduced to the
farm. Outside of doing a restore to the DS, there is no way of downgrading
the DS if you remove the server.
If your going to run a mixed version environment, it is best practice to
have a zone for each version. So if your farm is PS3 and PS4 (assuming PS3
is NOT running SP1), then you'd have a zone for PS3 and a zone for PS4. A
zone REQUIRES a ZDC so if you have a PS4 zone, you have a PS4 ZDC for that
zone. There are too many issues with mixing a single zone with multiple
versions. this comes from cold, hard experience.

Always keep the versions in their own zones. That eliminates the problems.

It's a different structure isn't it?
I know for instance that there is a schema change in R02 for CPS4 which can
cause problems if the servers aren't updated correctly. Should always have
your Dcs on the latest service pack revision - but this won't be the case
in the new farm.
And your obviously getting some timeout issues.
For example, in a migration at least your Dcs, data connection servers and
metric servers should be PS4 first - if you've gone PS3 for everything
that's probably not going to be pretty.

I didn't recreate the datastore when I downgraded or when I later rebuilt
from fresh. I thought the datastore would remain compatible. I may create a
new farm on a new datastore and move the servers into it tomorrow. The
difficulty is that we are in healthcare and need the farm 25/8.

Indeed - or did you re-create the datastore, but use the old .dsn?

What's your datastore?
Did you recreate your datastore when you downgraded from PS4 to PS3? What
was your procedure? Perhaps there was a misstep that could explain what's
happening...

Using qwinsta I was seeing a couple of down sessions, then a number of
sessions hit conn and move no further. At that point the server is accepting
load, but unable to process it.
Mind, I think mine is related to session logons coming in too fast. I also
had a problem with a logon script attempting to map to a drive that didn't
actually exist - this was for all users and no help at all to the logon
process.
What happens if you *don't* put on the hotfixes?
