All nuclei of an Adabas Parallel Services cluster must migrate to version 7.5 at one time. Different releases of Parallel Services cannot coexist in the same cluster.
It is possible to run Adabas Parallel Services 7.4 with the ADASVC from the Adabas Solution tape containing the data set ADA742.LX01. If you run multiple databases with Parallel Services 7.4, you can migrate them to version 7.5 one by one.
