I'm executing the checklist to upgrade a MICS test complex from SAS 9.2 to 9.4. Several steps for upgrading specific datasets to 9.4 are marked as Optional. What should we consider in deciding whether to exercise that option? Is there a possibility of error if we don't convert? Will MICS run better if we do convert? We see this on SCREENS, the unit MUOLIBs, the unit database files and some MICSF user private SAS catalogs..
Do a proc contents on the DB's in question .. If the Engine is either BASE or V9
Then there is no need to convert..
