Using existing session to create Session Channel|OPC UA Standard|Forum|OPC Foundation

Hi,

I had a query on using existing session to create a sessionchannel. Below are the steps -

1. Create securechannel using an endpoint with security mode None. [secureChannel1]
2. Create session.
3. Create SessionChannel using this session and securechannel. [sessionChannel1]
4. Change the endpoint to the one using security mode Sign.
5. Close old securechannel and create new one using this endpoint.[secureChannel2]
6. Create SessionChannel using the old session and new securechannel as below - sessionChannel1.getSession().createSessionChannel(secureChannel2, client)

Is it correct to perform #6 after changing the security mode from None to Sign. I think the endpoint should not be changed in this case. Please confirm.
