How to Migrate SharePoint Site Collections Between Content Databases?

A SharePoint site collection includes all of your sites, lists, content, and templates, which makes it the most crucial part of your SharePoint environment. But there are certain circumstances in which you might need to migrate your site collection from one database to another. For instance, if a site collection outgrows the content database on which it resides, then you need to move it to a larger content database.

In this article, we will discuss how you can migrate a site collection from one database to another with PowerShell Commands. Also, we have provided an alternate solution to migrate SharePoint site collection from one content database to another.

Things to know before migrating Site Collection

Before beginning the migration, make sure that the following conditions are true:

  • A content database should already exist as a destination
  • The source and destination content database must be located on the same instance of SQL server
  • The source and destination content database must be attached to the same web application

Also, it is necessary to analyze the size of the source site collection because the auditing data is also copied while moving the site collection. If the auditing data is large, you can archive and trim the audit data using PowerShell.

To find the size of a site collection, run the below command in SharePoint Management Shell:
$used = (Get-SPSiteAdministration -Identity <http://ServerName/Sites/SiteName>).DiskUsed

Moving Site Collection between Content Databases

To move the site collection, you need to use Move-SPSite command in PowerShell. Using this command, you can move a single site collection as well as multiple site collections to a new content database.

Moving single-site collection

To move a single SharePoint site collection, you need to have the following memberships – securityadmin fixed server role, db_owner fixed database role, and the administrator group.

  • Open SharePoint Management Shell and type the below command in PowerShell command prompt:
    Move-SPSite <http://ServerName/Sites/SiteName> -DestinationDatabase <DestinationContentDb>
    Here, http://ServerName/Sites/SiteName is the name of a site collection, DestinationContentDb is the name of the destination content database.
Moving multiple site collections
You need to have the same memberships as mentioned above to move multiple site collections from one content database to another.
  • Open SharePoint Management Shell and type the below command in PowerShell command prompt:
    Get-SPSite -ContentDatabase <SourceContentDb> | Move-SPSite -DestinationDatabase <DestinationContentDb&gt;
    Here, SourceContentDb is the name of original content database and DestinationContentDb is the name of destination content database.

Using these commands, you can easily migrate site collection from one content database to another. However, there is another method to migrate site collection from one server to another – using backup and restore of SharePoint site collection.

With backup & restore method, you need to backup SharePoint Site collection using PowerShell, and then restore the Site Collection to SharePoint server with the same technique.
