Adabas and Event Replicator Server Compatibility

The following rules must be followed when using an Adabas source database with an Event Replicator Server:

The Event Replicator for Adabas version used by the Event Replicator Server must be greater than or equal to the Event Replicator version used in the source Adabas nucleus.

Note:
The term "or later" in the table above indicates a later SM within the same version and release of the product unless otherwise noted.

These combinations provide you with flexibility when upgrading your levels of Adabas and Event Replicator. If you are an existing user of Event Replicator, you might have multiple Adabas 8.3 nuclei running replication (REPLICATION=YES) and Event Replicator 3.6 or 3.7. You might also have multiple Event Replicator Servers running with Adabas 8.4 and Event Replicator 3.7 or 3.8. The compatibility combinations listed above mean you are not forced to upgrade all of your Adabas nuclei and Event Replicator Servers at the same time. You might first upgrade your Event Replicator Server software before you upgrade your Adabas nuclei later. In addition, you can upgrade one Adabas nucleus at a time.
