Hello,

I'm experiencing a problem with SQL Replication while upgrading to SCCM CB 1802. SCCM hierarchy consist of 1 CAS and 4 primary servers. SQL version is SQL 2012 Sp4 on CAS and Primary servers on SQL 2012 Sp1 (plan to upgrade to SP4 prior to upgrade to 1802).

CAS upgrade went well with no issue, all replication appears OK. however the issue is with all Primary servers.

Link Status: Link is being configured (Initializing the data between the parent and child site). it's in the same state for last 48 hours.

No error reported in rcm log. one of the suggestion was to upgrade primary to 1802 to fix the issue. Just want to make sure that wont break something else.

Please advice.

Thanks,

Sreedhar

Hi SreedharB,

What is the version of your site server operating system?
https://docs.microsoft.com/en-us/sccm/core/plan-design/configs/supported-operating-systems-for-site-system-servers

"plan to upgrade to SP4 prior to upgrade to 1802" Did you have upgraded them to SP4?
https://docs.microsoft.com/en-us/sccm/core/plan-design/configs/support-for-sql-server-versions

What's the link speed between the sites server? If it's slow, the replicaiton maybe will take some days to complete. Please refer to this link for a similar issue.

In addtion,you could also disable the Firewall/AV to avoid some impact.
Hope it helps.

Best regards,

I highly recommend that open a case with Microsoft as no one here can really help you with replication as it's a very complicated process.

I had opened ticket with Microsoft,

Issue was resolved as it's expected behavior in SCCM hierarchy. this is because SCCM CB has more feature and some of the replication groups were not in SCCM 2012. Because of this reason, you see this behavior. After upgrading primary server, replication link is active on primary server.

Thanks,
