SQL Server Database Migration Issues and Reasons

  • As we all know that Microsoft officially stopped support for old SQL Server versions such as SQL Server 2008/R2 and SQL Server 2012. Thus users don’t want to compromise security hence they may prefer SQL server database migration from 2008/2012 to the latest SQL editions.
  • Multiple small-sized businesses are in a growing phase and using SQL Server locally. But for future use, they want to set up a virtual environment with upgraded hardware. Hence, they prefer to migrate SQL server database instances from local to virtual.
  • Several organizations want to reduce their per-year Windows OS license costs for multiple devices that use Microsoft SQL Server to handle automation transactions. Instead of this nowadays users prefer to setup a SAN (storage area network).
  • Sometimes companies and professionals have the desire to move SQL server databases from local servers to cloud-hosted data centers because of scalable features. Hence users search for SQL Server data center migration steps.

Types of Database Migration in SQL Server

Different business enterprises prefer to do various types of database migration in SQL Server as per work requirements. Here we are discussing a few major types of SQL migration.

Storage Migration

It refers to moving SQL Server data from one device to another such as hard drives, solid state drives, on-premise servers, and cloud-hosted servers.

Data Migration

Data migration refers if someone wants to do SQL Server data migration between two vendors and software providers.

Business Process Migration

If two or more businesses complete the merger or acquisition formalities then the parent company wants to merge the business process which is called business process migration.

Application Migration

If someone decided to change applications or operating systems environment that is considered application migration. For example, SQL Server database migration from 2012 to 2019.

Note: You can repeat above mentioned two phases for completing the SQL server database migration process for all databases. Now you have successfully moved your SQL Server database, but you cannot use it because your login details are not yet connected with migrated associated database(s). Hence, first, verify your SQL logins.

  1. Open SQL Server Management Studio at the destination server.
  2. Choose Server >> Security >> Logins here you can see previous logins are not transferred here.
  3. So, choose Server >> Databases >> Your Database >> Security >> Users, now you can correct the logins associated with the database.
  4. If you have one or two users then you can also delete the users associated with server databases.
  5. Go to Servers >> Databases >> Your Database >> Security >> Users >> Recreate Users in Server >> Security >> Login.
