Pros & Cons of the above-mentioned method

While the above mentioned manual procedure comes with the plus points of being free of cost and readily available, it suffers from the following limitations:

  1. It is too lengthy and complicated
  2. Configuration problems in any version of SQL Server can prevent you from upgrading
  3. You can never really be sure if and when any of the following SQL database upgrading issues may arise:
    • Database Engine upgrade issues
    • Late-breaking upgrade issues
    • Replication Upgrade issues
    • Full-text search upgrade issues
    • SQL Server Agent upgrade issues
    • Reporting Services upgrade issues
  4. Moreover, before performing this procedure, you must ensure that the account you’re using for the upgrade is a member of the sysadmin fixed server role on both the source and destination servers

These shortcomings of the procedure are sufficient to prompt the need of an easier method (third-party tool) to perform the upgrade. Moreover, the biggest risk that this method carries is that if the upgrade gets interrupted due to any reason, the SQL Server database will end up getting corrupted.
