Migrating from SfB 2015 to MS Teams
We are trying to migrate from SfB 2015 to Ms Teams with my client, all prerequisites have been set up and when using the powershell Move-CsUser command, we get an error message: So we follo...
Hi Noureddine,
If the users are already using Microsoft Teams Online are you in Island mode or are you on Teams Only mode in the Teams Admin Center. I wanted to understand the overall architecture before I recommend the solution.
Additionally what is the reason why you want to move the users from SFB 2015 to Teams is it due that we are trying to migrate our telephony?

Hi Satish,
At first I thank you for taking the time to answer me !
yes the coexistence mode is Island.
I went ahead on my own and decided to migrate 5 users to the pilot.
by removing the MSRTCSIP attributes, keeping only those highlighted in yellow and having replaced the SRV value with sipfed.online.lync.com.
yes we move the telephony to Teams in Direct routing.
- Hi,
The migration from the SFB 2015 will only be successful if the users values are intact and hybrid is built between SFB onpremises and Microsoft Teams. Since you are users are already in the Cloud I would recommend to configure the Direct Routing using the SBC and provide the users with the Telephony from the cloud instead of on-premises Cloud. As there would be conflict or users while you try to migrate the users with the users already in the cloud.

Satish U- Hi Satish,
Thank you for your feedback but you didn't answer my question, the direct routing and sbc are already implemented and there is already a hybridisation between SfB and Teams since more than 1 year.
As I cannot upgrade the SfB server to use the migration tools, I would like to use another method such as deleting the msRTCSIP attributes with a script. I wanted to know if anyone has already done this and what the consequences are, apart from not being able to retrieve favourites, contacts, history, etc., which does not seem to bother my client.
