Willie, It's been a long, long time since I did this, but there are a few extra weapons in the arsenal nowadays.
There is not much that is going to actually "break" when you go from 3380 to 3390. VSAM will look after itself and flat files will have wasted space. The main things that will break are DA files. First thing would be to think about your default device geometry in SMS. Your allocation will be influenced by this. I would suggest leaving it as 3380 until your conversion is complete, and then change to 3390. DCOLLECT is your friend. SMF records are your second best friend. You can use DCOLLECT to audit the attributes of your files. You can find and DA files here and check if they need any special attention. You can also use this DCOLLECT to identify your largest files. Just focusing on the largest files that make up 80% of allocated space will get the most gain for the least effort. Once you have found the largest files in DCOLLECT, use the Type 14, 15, and 6n records to find the job that allocates them. Replace the BLKSIZE parm with the DSORG parm and they will be created with SDB. The small datasets can be an exercise for a later time.
