V6.3
There is only one difference between and upgrade from V6.1 and V6.2 and an upgrade from V6.3 and that difference applies only to user using the CommServer functionality of TransLution. This is where TransLution is used to read data from scales into an input step on an EazyTouch device.
When upgrading from any version prior to V6.3 means that all scales will need to be re-configured to use the new communication mechanism. This only impacts sites which are using scales.
All other upgrade issues are the same as if you were upgrading from V6.1 or V6.2. Please read the V6.1/2 notes here as regards to updating EazyTouch.
