Subject: Re: 8.0.2 - 5.0.11 replication broken after upgrade
Hans,
I can see your dilemma, with Domino Server A’s Operating System & Lotus Domino release(s) being Out of Support. However, replicating a Domino v5.0.x Server with a Domino v8.0.x Server is probably not a good idea for several reasons relating to differences in Database Design (i.e. Templates) and raw Functionality of the two versions.
That said, you should focus on upgrading the Operating System of Domino Server A to at-least V5R2, V5R3, or V5R4. This would allow you to then upgrade the Domino v5.0.11 Server to v6.5.x or v7.0.x. With Domino Server A at a 6.5.x release, you should be able to achieve successful Replication amongst Domino Servers A, B, and C.
Now, if the Operating System on Domino Server A cannot be upgraded to V5R2, V5R3, or V5R4 due to Hardware-related reasons, then you could simply migrate Domino Server A to an iSeries with a newer version of i5/OS.
In summary, don’t focus on achieving Replication between 5.0.11 and 8.0.2 - you’re only going to run into more headaches which will be far greater to resolve than this problem. Instead, focus on moving towards a supported-environment.
