Planning on migrating but are still on v7.6...
 
We have a production server that although on SS 2005 sp4 - has high availability.
 
We have some test/staging servers with SS 2008 R2.
 
Although the ideal situation would to have all environments match database servers - some things are not possible budget wise...
 
Most times I will deploy from staging to prod, but there are cases that I would do the opposite to verify that I have the last updated prod map.  Is this a huge problem in terms of deploying across databases?  Will one map work differently from another just because the SS versions are different?
