What method did you use to port the database?Remember to use a schema comparison tool to insure things like indexes, table options, statistics, constraints, plan guides, etc. are all the same before attempting a baseline comparison. Also the method used to copy table data to the new instance (if that's the case) could have resulted in fragmentation.
This is a dev system and I just ran an upgrade from 2012 to 2014 as the SSD is getting slightly cramped. Part of the exercise was to test the effects of the upgrade on the surrounding systems, even kept the instance name the same. So far everything is jolly, figured out that it was me missing something, not any changes in the behaviour:hehe:
