Hi

I have a web application, with 300 Site collection, with 5 TB of data in total in production environment. Site collection upgrade to SP 2013 is taking around 6 days to upgrade all site collection. Please suggest the system resources/ hardware required to the upgrade it in 3 days. Kindly share the Microsoft article in support of it, if any.

Your help will be greatly appreciated.

Hi,

As I understand, you want to reduce the time when upgrading the site collections to SharePoint 2013.

 If you want to upgrade to SharePoint 2013, you could use the database-attach method. The upgrade process separates the upgrade of database content schema from the upgrades of site collections. And this method comes with some new enhancements for performing site collection upgrades.

For more detailed information, you could refer to the articles below.
