The first question that I have in mind before continuing this post is:
Q: Is it possible to have multiple instances for the same SharePoint farm?
A: Yes it is possible, we can have more than one SQL instance where we can store the content databases.
If you want to transfer a SharePoint content database from one instance to another you can use the following procedure:
| On the SQL server1. Backup the content database.
2. Restore the database on the second instance 3. Add the same permissions for the content database that you had on the source instance. On the SharePoint Server 4. Detach the content database from the web application : stsadm.exe -o deletecontentdb -url <URL name> -databasename <database name> – additional information in the following article http://technet.microsoft.com/en-us/library/cc262449(v=office.12).aspx 5. Attach the content database from the new instance to your web application : stsadm.exe -o addcontentdb -url <URL name> -databasename <database name> -databaseserver <database server name> – Additional info in the following article http://technet.microsoft.com/en-us/library/cc263422(v=office.12).aspx Additional information regarding backup restore procedure in the following article http://technet.microsoft.com/en-us/library/cc671616(v=office.12).aspx Back up and restore databases (Office SharePoint Server) |
Second question, is it possible to have the instances on different SQL versions?
Yes it is, but you need to check the compatibility of the SharePoint product with the SQL version.
Here you have a table with the compatibility between different SharePoint versions and SQL
SharePoint 2007
