I want to restore a site collection in my middle environment and have entered the following Power Shell command. But I am facing an error that says restore SPSITE 0x80070003. How can I solve the problem?
When restoring a site collection from another farm, which was an older version of CU / Patch, this error occurred.
Optional workaround if you do not want to update the other farm:
Create a test web application in the new battery
In SQL, restore the original database with the site collection that you want to restore.
Upgrade ID SPContentDatabase <ID GUID>
SPSite backup – Identity “http://contoso-a.com/” – Path E: \ contosobackup.bak
Restore SPSite ‘http://contoso-b.com/’ -Path E: \ contosobackup.bak –Force
