I know you're about to switch over to the new servers, but in doing last minute checks of the data I noticed two things:

1. You seem to provide more data for a stock via TCP/IP Historical (thanks!).
2. Volumes (and some prices) provided for TCP/IP Historical is always different between the two servers. Not by much, but a couple of thousand shares.

Here is Microsoft 60 minute data from the new servers:
2007-06-07 07:00:00,30.1600,30.1600,30.1600,30.1600,100,100;

Are they using the same datasource?

This is something that the server team was already aware of.

They advised that going forward (from the time of this post) the data should match.
