Switching from using a single tenant to multi tenant HelseID client towards SFM

When an organization already exixt in SFM using Single tenant, the SFM-id can be reused as a Journal-id when going over to using Multitenant. In this way, the new multit tenant token will point to the initial instance and you will be able to continue access to all the existing data (instead of creating a new instance).  

Here is an example of the multi tenancy token that provides access to the instance created initially: (note that SFM-id have no meaning in this case)
