Is it worth getting rid of linux heterogeneity in the network?

Question

linux

There is a relatively small working network for 120 machines. the AD-server+RDP+MSSQL lives in it. In addition to all this, existing Linux systems run on debian and centos (50/50 approximately) + a couple of NAS storages. In view of a little practical experience with Linux, there is an idea to transfer everything to debian and take a thorough study of the system From and To based on Debian.
Distribution by destination is such
Debian: OTRS
smb-server
Racktables
proxy
backup
-server
Centos:
DHCP
DNS
ZABBIX
MYSQL
Test server
The transfer should not bring big problems (DHCP,DNS - configs look the same, MYSQL databases only, ZABBIX-it and on debian Zabbix ).
How do you deal with flavors of Linux-OS in a live environment? Is it worth bringing everything to the same type of OS?

Answer 1

Transfer everything to one distribution. On Debian, of course, not rpm-hell.

Answer 2

The choice of distribution kit is a strongly religious issue, you should not open a branch of the ENT here. But it is definitely necessary to calmly and systematically eliminate the zoo.

Answer 3

Debian can only be wished upon an enemy.
While Linux is still alive. But there are only 2 distributions: slack and gent. The rest have already rolled into the plunger.

Answer 4

Usually everything is on the same distribution (maximum - there is a spread of versions). This is a consequence of the principle "put the distribution that you know better."
There is a second principle "works - do not touch".
So, two conflicting arguments.
You can do the transition, but not by tearing it down and installing a new version, but by raising an instance of a server role next to it, followed by a load transfer.
And don't forget about backups!

Answer 5

It would be logical all the same to transfer everything to centos, and not to debian.

Answer 6

IMHO if not "impatient" then do not rush. And there, after two or three years, you will stop noticing the difference at all :)
