We recently upgraded to ECC6.0 and during the course of that upgrade, created a new development environment. Previous to the upgrade, they system was DEV-200 and a T78NR table entry exists for that system with prefix 900. Our new development system is called D01-200 and no entry exists yet for that system.
My questions is this? Should I leave the old DEV 900 prefix in the table and create a new prefix for the D01 system? Or, should I delete the DEV 999 entry in the table and create a new D01 999 entry?
I want to make sure I don't have any issues in maintaining previously developed workflows if necessary.
