1. If that is the actual command, the TGTRLS parameter could be updated
to reflect the current releases of your systems (V7R1 instead of V5R4).
You aren't really hurting anything if you don't change it but if you get an
object that requires a higher release of OS support than V5R4, you won't be
able to save it with this particular command due to the V5R4 specification.

2. If you're happy with the process as it is - you can make the suggested
tweaks and proceed as usual

As has been stated the commands were not changed since the source systems
went to 7.1. So during the time when the source was 7.1 the target was
earlier but no issues occurred during the time until the target was also
upgraded.

3. Yes, you have the concept - this is a differential save. SAVOBJ and
SAVCHGOBJ are both restored with the RSTOBJ command - it will restore
objects from your SAVF regardless of how they were saved. You can also use
RSTOBJ to restore objects saved with the SAVLIB command should you perform
a SAVLIB and only need to restore 1 or 2 objects rather than the entire
library.

Thanks I have asked the team to look at it but have to be diplomatic since
I am consultant, not a perm employee and don't want to tell the
organisation staff how to suck eggs :-( Still the weight of opinion on this
thread suggests that this is worth asking. Over dark fibre and GbE it was
never an issue with the 30G file taking only 20 minutes to send to the
target system.

4. see #3 above.

Do you have BRMS on your system? (GO LICPGM option 10 - look for
5770-BR1). If so, is it being used? You referenced BRMS in your initial
email, which brought about a couple of responses regarding its' use in
resolving your issue. If you have BRMS, you may wish to review those
responses.

We do and use it regularly to backup the data to a ProtecTier VTL. But the

target system does not have a VTL. If the differential save works that will
be fine for the time we need to do this. The goal is to migrate the entire
system to a separate prod and DR environment and once that is done, there
will be no file transfers required.

Thanks,
