[OpenID] query regarding OP migration

[Nate Klingenstein]

Babu,

The short answer: "yes, but."  It is possible to address this use  
case with delegation.  It's a good feature but may be too advanced  
for some users.  It's certainly not standard practice.  This Wiki  
article might help:

Remember that this needs to be part of the initial setup.  This is  
because once the RP has cached an identifier associated with an  
account, it's difficult to reconfigure that link.  That OpenID is  
your login.  How do you prove that a different OpenID is the correct  
new identifier?  Unless your old, unloved provider is willing to  
help, manual reconciliation is the only way, in many cases, and  
that's a really expensive and difficult process.

Take care,
Nate.
