Hi, I need your help, im administrating various mikrotik hardware, how to prevent other administrators from updating mikrotik, an example, im upgrading all the mk´s to the version 6.44.5 Long Term, the other administrators are upgrading other mikrotik to 6.45.6 stable, i dont like it, how to disable the option to upgrade?, An Script?, thanks in advance! 
Talk with the other administrators and both agree on what version to upgrade your routers…
Probably the best advice:
But, if you control the other routers, you can restrict the permissions. I think upgrade is a “policy” right so if you assign the admins to a group without that permission, that might work too. See: https://wiki.mikrotik.com/wiki/Manual:Router_AAA
Thank you!1
