Upgrading Sage CRM from older versions.

When upgrading systems, I have always walked upgrades through each version to the final desired version.  However, I am wondering if this is necessary for the latest versions.

If I recall correctly, somewhere between 7.2 and Sage CRM 2017, there were some major changes in the database and it was necessary to step through each version to get to Sage CRM 2017.

However, if a customer is currently on Sage CRM 2017, can they go directly to Sage CRM 2019?  Or should they be upgraded to Sage CRM 2018 first and then Sage CRM 2019?

Any assistance to clarify this for me is greatly appreciated!  Thank you!
