Aftermath of Binding new template to existing networks

[Rahali]

Hi guys ,

I'm still new to Meraki's world and I have a question regarding Org templates , so my client want to have a new template created and configured (mostly layer 3/7 ACL's and policies) and associate it to existing pre configured-operational  networks .

My question to you guys is if i bind this template with the existing networks what kind of changes will happened to those networks knowing that i want their VLAN's/SSID ect to stay the same only affect groupe policies , ACL's and similar options .

Hope my question is clear , Thanks in advance .

Are you talking about MX specifically? If so, it will change practically everything, addressing the SVIs, port configurations, rules, etc.

My advice is to do a test first and also do it within a maintenance window.

Thanks for the reply, yes big part of it about the MX for example we need to apply layer 7 acls on all of the networks in the ORG , that's why i thought of the template but as you said if it's gonna change the config on existing networks and have 20 site down then it's not worth it .

Can you please recommend a solution for applying group policy/acls on all networks in the org beside the template option ?

Thanks
