SSIS package compare
I would like to suggest that SQL compare tool also have to support SSIS package compare. Currently I am at the position that I have to compare SSIS packages between two servers and find out if any SSIS packages missing plus if any SSIS packages on old version etc. Currently I am talking about SSIS packages reside in MSDB but even if it can be compare between file system, that will be great.
Also within the SSIS Catalog database.
Have you tried SSIS Catalog Compare? http://sqlblog.com/blogs/andy_leonard/archive/2015/10/12/ssis-catalog-compare.aspx
