looking for some advice, our app use parse server (IOS, Android) with coding in Angular JS. Recently our developers recommend that we migrate away from parse server and MongoDB and build something using NodeJS with an RDMS database. Obviously this is costly, the main reason they recommend a migration is because the Angular Js is no longer relevant. So I am asking the question to the community is a migration needed ?. Can we continue using Parse and update the Angular JS to Angular 13.
Also to note our android and web applications performance has degraded over the years.
