Migrate a Cloud Site from MSSQL2005 to MSSQL2008
Note: This article is written for our Cloud Sites Control Panel. You can get to it from the Cloud Control Panel by clicking Rackspace Cloud in the upper-left corner and selecting Cloud Sites. You can also navigate directly to https://manage.rackspacecloud.com/.
Note: If the procedure is followed correctly, site impact during the migration process should be minimal. We suggest that you perform this migration at a non-peak time to minimize business impact.
- To limit the traffic to your database, set your site’s default page to reflect that it is currently undergoing maintenance.
- Confirm that your current hosting plan has an adequate number of databases allotted. You might need to add additional databases to the plan to perform this migration successfully.
- If you created any full text catalogs, you must drop them before making a backup of your 2005 database. While SQL 2008 does support full text catalogs, our current tools do not allow for them to be restored if they are in the backup file. Once you have restored to the new MSSQL2008 location, add your full text catalogs. The information at the following links assists you in completing this task:
Set the database to
READ-ONLYmode to ensure that there are no updates done to the database while the migration is performed with the following query:
ALTER DATABASE [NumXYZ_OldDbName] SET READ_ONLY
Note: Only set the database to READ_ONLY after making the backup. Otherwise, you won’t be able to log into the new database.
When the new database is restored, set it to Read-Write with the following command:
ALTER DATABASE [NumXYZ_NewDbName] SET READ_WRITE
Cloud Site migration steps
Create a new MSSQL 2008 database in the Cloud Sites Control Panel under the Features tab of the domain that your MSSQL2005 database is on.
After the database has been created, view its properties (as follows) and note the change in the hostname. You will need to change any connection strings you have to the database and this information will be required. The information for you database will vary from the image depending on the data center in which your account is hosted.
Use the web-based admin tool, MyLittleAdmin, to back up your MSSQL 2005 database. The link for the online tool can be found in your Cloud Sites Control Panel by clicking on the database under the Features tab. For this backup, add
mlbto the end of the URL. It is important to add this to the URL and not to go through the standard MyLittleAdmin link found in your Cloud Sites Control Panel. Using the links instead of adding the
mlbmight cause session issues between the two MyLittleAdmin versions. For example:
Log in to your original MSSQL 2005 source database.
Back up your MSSQL 2005 database with the MyLittleAdmin tool. When the backup has completed, click on the file link to save the backup file to your local machine.
Log in to the MyLittleAdmin link again using your MSSQL 2008 database and login. Remember that the login you use to restore becomes the new owner of the database. Choose restore, upload the backup file you just downloaded in Step 5, and then proceed with the restore.
The restore tool might notify you that the previous users have no login mapping on the new SQL 2008 cluster. At this point your new database is ready. The only access allowed at this point is the owner login that you used to restore the database. If you need to change the owner to another login that you created in the control panel or remap users in your database to new logins, refer to the article, How to Change ownership and remap database users using the web based admin tool for MSSQL..
Once the migration is complete, update all connection strings to point to the new database. After you verify that everything is working from the MSSQL2008 database, delete your MSSQL2005 database and confirm with Cloud Sites Support that the migration is complete. Doing so ensures that you are not billed for the additional database use in the future.
