As has been announced this July, Microsoft is retiring Field Service On Prem, the package installation won't be available next year as well as the mobile application (Xamarin). MS recommends upgrading to the cloud. However, some organizations prefer to use the on perm version especially government sectors. We have a requirement to build Field Service app on prem but we can not proceed due to the retirement, as by next year users won't be able to download the mobile application and also Microsoft won't support the product anymore.
What would you recommend on this matter, would you suggest customizing the app from scratch? meaning create custom entities to represent Work Orders, Resources, etc. And build the schedule board by using a web resource (would be very complicated), then connect to another mobile app provider like Resco. This is one approach, another is use another product (other than MS), only issue is that this government agency is already using MS Dynamics products like customer service and sales, so they want to connect Field Service to these applications (to use cases, contacts,....), would this be possible if anther product is used? if so, could you please recommend one.
