Speeding an Oracle Calendar to #MSFTExchange Migration by Parallel Insertions

If you have more than a few hundred users, you can run multiple instances of the Oracle Calendar Server to Microsoft Exchange migration code.

Let's say you have 1000 users and want to break it down by half.  Say from A to M and N through Z.  You can set up two separate instances as follows:

Who "Blank" to M?  Because numbers sort BEFORE "A" so things beginning with numbers are lost if you do not do "Blank" as your start.

Then "N" to "Z":

Just to be safe I'd run each of these on separate machines, but you use the SAME mapping tables for each.

Make sense?

Oh -- and if you want to insert just ONE calendar to test, this is the way to do it:
Put the same name in each endpoint box.

And this is an Oracle Calendar to Office 365 migration in action:
