    Hi @Nilesh Mahesh Verma ,

    You can install the latest cumulative update depending on your version.
    Here are the build versions of SQL Server 2016: KB3177312 - SQL Server 2016 build versions
    You can upgrade SP2-GDR to SP3 and then install GDR.

    Please see this image to help you have a better understanding.

    Note: GDR (General Distribution Release) is different from CU. Each latest CU contains cumulative updates based on RTM/SP. GDR only contains serious updates.

    Best regards,
    Seeya

    Thanks for your reply, @Seeya Xi-MSFT !

    We have three environment - 1. Prod, 2. Dev, 3. Replica; and we have installed same SQL version in all three servers. We are having a database with same structure and data on both server- Prod and Dev.

    When I'm trying to replicate Prod database to Replica server, we are facing issue, but it got succeed in case of Dev database to Replica. I don't think there should be any SQL Server version issue here.

    I'm looking forward for you suggestion here.

    Regards,
    Nilesh
