  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,
  Yuxiang

  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,

  Sreedhar
