Replace Windows Servers with UCS - How would you do it?

Hello :slight_smile:

I want to replace my Windows Servers 2016 with an fresh UCS installation.
As it is my private home system, i have no problem to start with a fresh UCS system :slight_smile:
Actually i have 3 Windows 2016 Servers with forest level 2012_R2.
I tried to connect UCS to this, but it fails, so i decited not to focus on migration.

My Servers are as followed:
1x Windows Server 2016 as DC
1x Windows Server 2016 running Exchange 2016
1x Windows Server 2012 R2 as file server, also running an DMS software (EcoDMS)

All servers are running on a HP MicroServer Gen 8 with 16GB Ram, Celeron 1610T, 4x 4TB HDD as Raid1 (8TB total) and ESXi on a 250GB SSD in the ODD port of the server.
ESXi is running from the internal MicroSD card.

I want to start on the same server with Proxmox, which will be placed on the SSD with all coming VMs. There is also a NAS which will be the backup place for the VMs of the SSD.
The HDDs will be the data store for the fileserver.

My thoughts are now as followed:
1x UCS as Master Server (32GB HDD)
1x UCS as Member Server for Kopano as Mail Server (100GB HDD)
1x UCS as Member Server for File Server + DMS software (Not sure which software, i guess only UCS and some shares to the Datastore HDDs?) (32GB + 8TB Datastore)

Does it make sense doeing it like this or what would be a better solution in your eyes?

With best regards,

Hello. I’ve been running multiple Proxmox instances for many years now and 4 UCS VMs as a test for almost 3 years, but mainly using AD and mail (Postfix+Dovecot) components. Right now, I’m putting together a new set of UCS with clean install of v.5. The setup will be used in a small environment of ~20 people. So, multiple UCS servers seem like an overkill for one user. But, hey, if you want, do it. Proxmox + UCS are very affordable open-source solutions. :slight_smile:

UCS1 - primary directory node
UCS2 - backup directory node
UCS3 - member node - file server
UCS4 - replica directory node - mail

I run Proxmox on SSD with ZFS in raid-10 and have no complains with performance. All Proxmox VMs are imaged to a NAS. A fresh PDN install is about 5GB. It uses virtually no SWAP. The 3 year old PDN that I just upgraded from 4.8 to 5.0 has a little 10GB used space. UCS in such a role is doing well with 4GB RAM.

I have not played with file sharing much, just finished creating one share yesterday to make sure win7 and win10 clients can see it after starting with Windows logon script.

I’m not familiar with Kopano. I’m hesitant to commit to solutions that seem a bit bloated at the first glance. I could be wrong with such assessment, of course. I am a very long time Linux user (Debian for servers, which is what Proxmox is based on, and Arch as my own workstation) and try to use open source as much as possible. Thunderbird has been my mail client for a long time also. What UCS is missing at this moment is Roundcube or SOGo. I’d personally stick with Roundcube to have an ability to get to mail via a web browser and will try to create a separate VM with it and integrate with UCS LDAP. At my work, I have hard-to-die Outlook users. SOGo could work better for them as a web client. Another option is to utilize Nextcloud file sharing solution with few tricks to support CalDAV, CardDAV for Outlook users. Nextcloud is available as UCS app. I already have it running separately. Anyway… Sorry for too much info.

Good luck with your builds!
