Steps to follow for upgrade from 5.5 version to Nintex automation 5.7?

Does your current K2 server and SQL server support in place upgrade?

Or will you need to move K2 to a new server and then upgrade?

It is recommended that you create a snapshot of the K2 server and database backup before upgrading.

You can usually upgrade straight from 5.5 to 5.7.

I’m going to recommend looking over the Release Notes. In Five (5.6)+, there is a new support feature for SQL Server encryption. If the SQL box/instance has it, then you want to enable it in 5.6/5.7 platform.
