Hi
As long as we maintain our maintenance plan on the perpetual licenses, I assume this means we can use the latest version and any older versions we still have installed as long as our maintenance plan is still live?
The maintenance plan will give you a new release and also take one away. So that will be current release and 3 years back from then. So if you have 2020 then you can use 2019-2017.
When you stop the maintenance you lose the benefits of that license listed on this website --> https://www.autodesk.co.za/maintenance-plan
Edit - I found this on another forum --> https://knowledge.autodesk.com/customer-service/account-management/software-downloads/previous-versi...
What if I previously licensed a product—how many copies can I use?
You may continue to use previous versions of software previously licensed, installed and accessed, which are not listed on the previous version list, provided they were previously licensed, installed and accessed as part of your subscription or maintenance plan—and you do not exceed the number of licenses previously licensed by you or the number of your current licenses of that product covered by your active contract (whichever is lower). Additionally, you can continue access if you remain active on a subscription or on a maintenance plan. See applicable Autodesk Terms and Conditions for additional details.
For example:
You originally purchased ten licenses of an AutoCAD 2014 subscription. You then installed and accessed all ten licenses. You continued renewing your subscription for these ten licenses. When the current version becomes available, you decide to purchase five (5) more AutoCAD subscriptions. Now you have a total of 15 licenses.
