Ricki,
 
When we migrated from 6.3 to 7.0.02 we "flipped the switch".  Everyone was 
trained ahead of time and one sunday night I took our 6.3 environment down, 
copied over the data, changed the DNS alias from the old server to the new 
server and then disabled "admin-only" mode on the new server. (we were down 
about 8 hours)  We have a service desk with about 20 employees taking 400-600 
calls per day.  It was a little rocky the first few days but things smoothed 
out quickly.
 
Also, the gradual migration could cause confusion in your user base.  Unless 
you've configured your notifications to look exactly as they did before your 
end users will start to see email from a different address containing different 
information (depending on whether or not your using the email engine and how 
you've configured it)
 
IMHO the cons of a slow-drip migration heavily outweigh the risks of a "flip 
the switch" migration.
 
-Eli

Subject: Putting ARS 7.0.1 into production question


** 

Hello,

 

After some weeks of testing in a dev environment, we're about ready to put ARS 
7.0.1 along with Incident and Problem Management into production. I've purged 
the licenses from the current production server so we have 60 days to get 
everyone up and running on the new server.  The question is how to go about 
flipping the switch.

Management wants to slowly (over a 3 - 4 week period) migrate support people 
with fixed/floating licenses from the old server in order to not slow down 
production.  All of our customers are internal users and usually need help 
right away, not a few hours later.  Surely there must be a better way.  I think 
if everyone is trained on the new system we should be able to move everyone 
over at one time.  We have 4 - 5 people manning the phones at the Help Desk and 
they take approximately 150 calls per day, along with emails and forms for user 
access changes.  I can do a daily transfer of tickets remaining open to the new 
server but that's a nightmare in itself.  If two phone support people are on 
the old system and they get calls on tickets entered into the new system that 
day,  that customer will see a delay in service while waiting for the support 
person on the new system to get back to them.  Anyone have an idea that's 
probably staring me in the face?

 

Thanks,

Ricki Haines
