Hi

We have two SharePoint 2013 Farms and we are trying to Move a site collection (with all content) from one SharePoint farm  to another SharePoint Farm. Both the Farms have their own DB servers.

Can pls suggest how this can be achieved. Please elaborate the steps with any commands if applicable.

Thanks in advance.

Simply perform a backup and restore, if the sites are under ~75GB:

Backup-SPSite http://siteCollectionUrl -NoSiteLock -Path C:\backupfile.bak

Restore-SPSite http://newFarmSiteCollectionUrl -Path C:\backupfile.bak

I hope Trevor clarifies your concern to get this job done.

You can move site collections between databases in a SharePoint 2013 farm by using Windows PowerShell. You can also move site collections by using Backup and Restore procedures: https://technet.microsoft.com/en-us/library/cc825328.aspx
