I figured as much, export/import is not blazingly fast, so, 2020 is
probably a pretty good estimate.
Why? IBM charges about 3 times more in maintenance costs than SUN
(at
similar performance points)
this is quite a narrow view at TCO, and I guess you are willing to
ignore the cost of the migration.
My main argument is that solaris is a less commonly used platform for
TSM servers, so you are more on your own when it comes down to
platform specific issues. Also, I wouldn't be surprised if you're more
likely to run into bugs in the platform specific code. TSM, it seems,
is mainly developed on AIX and windows, and more thoroughly tested on
those platforms.
I'm still impressed by the stability of the AIX servers, even under
very heavy I/O load. I've seen more hardware issues on SUN hardware
than on p series. ANd, well, last time I checked the SUN hardware was
less suitable for heavy I/O loads, but that might have changed...
Thanks for the insights.

Hello,
TSM Server 5.5.0.3 running on AIX 5.3 ML6, clients are a mixed lot as
usual.
We are going to migrate this to a SUN Solaris Server, Solaris 5.10.
why? probably too late, but really, stick with AIX. I'd say this is
one of the least used platforms for TSM and probably less stable than
even windows ;-) You must have very strong reasons to go to solaris,
because you are in for a huge amount of work. Going to another
platform is not easy, nor is it quick.
Primary client is solaris, ~80TB active data, ~300TB of inactive/
archive
data.
export/import is the only way (or just starting over with an empty
database). Good luck, speak to you in 2020 or so when you're done (or
gave up) ;-) server to server exports are only possible if the target
server is at at least the same level as the source.
Can anyone point me to a Redbook or the section in the Admin Guide to
help me understand what I am going to have to do? So far, the Admin
Guide explains migrating, but, only to another system with the same
O/S.
