PST Migrations

Created: 14 Dec 2006 • Updated: 23 May 2010 | 3 comments

I know this is a tough thing to estimate, but does anyone have any rough numbers on how fast the PST migrator moves?

We are starting to plan out some PST migrations and I would like to roughly guess the timeframes associated with this task.

For example, 10 gb of PSTs takes 5 hours to collect and migrate into vault.

Are you doing server or client driven migrations? Either way the likely bottleneck will be the copy operation of PST data to the EV server. Once on the server I have seen 4-5GB per hour. One thing to remember is that PST migrations are a case of start, monitor, monitor, monitor, troubleshoot, monitor, wait and then pray everything goes smoothly. Don't box yourself into a corner by promising it will be done in a given time frame. Setup a pilot group that is representative of your org, track the migration process from this group and then extrapolate to the wider user base.

LOL, I love your description.

At this point I am leaning at server driven migrations.

Yes I am planning a pilot group and testing. Right now we are way in the preliminary planning steps and we are just trying to get rough ideas of the scope of this project.

Server migrations work well with PSTs in a central location but if this not the case I would almost always recommend attempting client driven migration first. Server driven requires that Outlook be shutdown in order to copy the PST and than can be a real pain to organize for many companies.
