Hi,
The declarative user profile is no more available from the version 24.0.1 I have it enabled.What are the consequences I would face as the feature is removed
It’s not removed, it’s now here by default, you can’t disable it.
So I had it in my enabled features and as you mentioned it is now here by default, now removing it from the enabled features,wouldn’t effect my upgrade anyway right?
You’ve already been pointed to the migration documentation which has a specific subsection about the Profile SPI changes which should answer all your questions: Upgrading Guide
