RE: Guidance on Mobile App Upgrade (v45 → v87) and Long-Term Support Strategy

Whether upgrading from v45 to v87 would require a complete or partial rewrite of our existing mobile custom code due to the transition to React. - most likely not much of your custom code will have to be rewritten. React was introduced mostly in new components/functionality, so your existing customizations are most likely not affected
Which legacy mobile customization frameworks or APIs are deprecated or no longer supported in the latest versions - it's hard to tell from top of my memory, most likely nothing major was deprecated
Recommended migration strategy or best practices for converting existing Cordova/Backbone-based customizations to the React-based mobile framework - see point number one. Each component will need to be managed by hand depending on kind of customization, there is no 'official' way unfortunately
Availability of any official documentation, migration guides, or tools to support this conversion - no special tools are available here
Which SugarCRM Mobile versions or upgrade paths are best suited for long-term stability and support - From my perspective, the best way for long-term stability would be to migrate codebase in a small steps with each new mobile SDK release to avoid big jumps (like in this case) that could introduce significant hurdles
See point 5
No official guidelines are available, so please stick to general engineering best-practices

Long-term roadmap for Sugar Mobile is not clear at this point. For now, no breaking changes are planned

Best regards, Eugene
