[Samba] Functional Levels

Hello List,

I would like to raise the Functional Level of two production 4.7.6-Ubuntu DCs to 2008R2.

There is a mix of Windows Server 2008 + 2012 performing RDS, Sage and SQL, along with a mix of Windows 7 and Windows 10 desktops all joined to the DOMAIN.

What do I need to be worried about when performing this?

(Obviously, the two DCs will be backed up and everything else switched off first :)

"Here's what we know so far..."

root at dc3:~# samba-tool domain level show
Domain and forest function level for domain 'DC=X,DC=com'
Forest function level: (Windows) 2003
Domain function level: (Windows) 2003

root at dc3:~# ldbsearch -H /var/lib/samba/private/sam.ldb -b 'cn=Schema,cn=Configuration,dc=X,dc=com' -s base objectVersion
# record 1
dn: CN=Schema,CN=Configuration,DC=X,DC=com
objectVersion: 47
