I am planning to upgrade the react-native from 0.51 to 0.62 for the iOS platform. Typically what is the duration it takes for an upgrade?
Can I carry out a staggered upgrade? Just to upgrade the react-native to the latest version and libraries to be upgraded later.
I can live with deprecated API if it doesn't break existing functionality or doesn't have performance issues.
Which is a better way: one version at a time or one portion of code at a time?
