[Samba] It is secure to transfer roles and demote DC?

[Federico Alberto Sayd]

Hello:

I want transfer FSMO roles from a DC and then demote it, I was reading 
the wiki and there is an advice about a bug [1] with samba-tool that 
prevents that two roles be transferred, when you use "samba-tool fsmo 
transfer".

The DC that I want to demote is also a file server. But if something 
goes wrong I don't want to reinstall the File Server. I can see that the 
bug is still open.
I am using samba 4.1.11 from Debian Backports.

Some news about it?

Thanks
