Hi Karthick,

I agree with Rick in advocating standing up a new environment and moving
your data to it. There are many advantages to doing thing this way and I
probably don't have to list them all here. Stand up a new environment, on a
new database,  install ARS, ITSM to each server in the group, get it
patched to the right versions, apply the customization you need to preserve
via overlays (some may be covered in the new version), then use rrr|Chive
or similar to move the data to the new environment.Perhaps use this as an
opportunity to archive old unnecessary data at the same time (eg old
notification logs). Using this approach you will be able to test your new
system in full prior to the big cutover weekend. On a big system it can
take time to synchronize the data but rrr|Chive's synctotarget feature can
be used to minimize any duplication of effort and this can all be done up
front.

There are (at least) a couple of gotchas to be aware of if you do stand up
a new server and move your data to it.

1. Some forms have had unique indexes added to the "Instance ID" field.
They probably should have been there all along but if you have somehow
allowed duplicate instance IDs to creep in (via "copy to new") then you
will need to clear this field and generate new IDs for the dupes when
moving data to the new system.

2. Doing an in-place upgrade to a system populated with data can take a
very long time and can timeout before completion. I presume the upgrades
can sometime do data conversions and this is the reason. I think in one
instance it tries to push fields to every row in a table in one transaction
and that kept repeating, timing out or reaching the filter limit before
rolling back. Best advice is to try and avoid doing an in-place upgrade to
systems with lots of data. Clear the data out of impacted tables, do the
upgrade and then replace the data. That's why it is best to do the patch
upgrades prior to moving data to new system.

3. Some of the same out of the box foundation data has different request
IDs between versions of ITSM. If you try and merge the foundation data
between 2 different releases of ITSM you can end up with duplicate
permission groups or similar. identify the real key and delete the dupes on
migration.

I'm sure there are some other gotchas and as Rick says when you start
combining changes to the data as you migrate things can get a little messy
but I think you may be surprised how easy it actually is to move the data
from one version of remedy to a new one.

rrr|Chive
