Transfer data through move to ios, facing error while transferring data

You may have to do that manually:

Move content manually from your Android device to your iPhone, iPad, or iPod touch - Apple Support

Are you manually transferring each type of data after the other, and getting the same error message just before finishing, no matter what kind of data? For example transferring photos, saving them to a folder on your computer, and then synchronising this folder to your iPhone, using iTunes or the Finder of your computer/Mac?

Still getting error message at very end of transfer (3 minutes left to transfer completion) and have restarted multiple times.
