I am using IBM MFP in my code and my current assignment involves migrating a project from MFP version v6.3 (Called as WorkLight) to Mobile First Platform v8.0.

During the migration process, the following Client API methods are considered as discontinued in v8.0. When I looked at IBM support site, it is told "No replacement". There is no more detail given on this. The methods are,

* WL.Client.getUserInfo
* WL.Client.updateUserInfo
* WL.Client.isUserAuthenticated

Does any one know what exactly this term "No replacement" mean? Does it mean the equivalent code has to be manually written by the developer who previously used WL.Client.getUserInfo?

This is the same case for other client API methods WL.Client.updateUserInfo & WL.Client.isUserAuthenticated? 

Please help. I have gone through the IBM support knowledge centre, I don't see any page that gives a detailed explanation of *"No replacement"*.
