We have a blog article on automating RouterOS upgrades:
https://unimus.net/blog/network-wide-mi ... grade.html
The article show how to setup a local RouterOS Package Source "server".
Unimus is then used to push package source configuration to the network, and tell the MikroTiks to update.
We will be puting out more blogs around automation (and other things) in the near future, stay tuned!
Any feedback is most welcome
