Trying to give some help but raising many doubts .....
1) The in-place upgrade is planned for Sme10 ? This time, apparently the main-stream Centos supports the 6->7 in place upgrade.
2) The lack of RAID1 install without manual trick is a part of developement still "work in progress" or Anaconda&C in their new Centos 7 flavor make harder to manage the install process ?
3) Samba: my great fear is that M$ expels definitively SMB1 support. Path to SMB2 is a safe path or not and involves Samba4 ?
4) Samba again: RH/Centos killed Samba4 support, some package (SOGO 4) needs Samba4 (i suppose for AD integration, right ?). This implies that we (and all Centos users) will never be able to have SOGO4 working ?
5) Collaboration software: COVID jam raised bunch of requests for remote access to files. Presently all request satisfied with OpenVpn or remote access with various ssh tricks. People are obviously interested with Google Tools, Teams, Flack and their related cloud storages. Which is the role that we can think for our SME in this new game ?
These are the first thoughts.
Presently trying to complete italian translations for contribs.
