Upgrading Adabas svc to 744


We will be upgrading the Adabas svc from 713 to 744, with adabas database remaining 713 on z/os 1.6. The installation guide mentions that the svc is downward compatible so this should work. Is there any particular issue that some of you guys experinced when doing this? We also use Adasql 231 with enlivening of cobol thru Endevor.
