Yes, contact us for a license conversion. You will need to convert to App Points when we begin hosting your MAS system.
We also have a script and process to calculate what number of App Points you are likely to need. It examines your top 10 peak usage times over the prior year and then determines the number of App Points that would have been checked out by users during those times, based on the security rights of those actual users.
Note that you will require App Points for your non-production MAS environments also. However, those non-prod environments will typically need a small allocation of concurrent App Points and starting with MAS 8.4 there is an option to share a pool of App Points across environments. Additionally, as of MAS 8.9, we can flag your non-Production environments as not needing to consume your App Points for “Install licenses” to install optional MAS modules.
