I have asked a similar question before and the answer works 100%. How can I move chatter free users to Community users
I should have spoken about more details before. In our community implementation we use the
contact associated to the user for some information and some other
related objects in the
VF tabs/pages we have.
contactId field on the user object is not
"updateable", is there any other way to move the
chatter free users to the
community license and also have a
contact associated to it?
