Hello Everyone,

Someone can help me saying the experience migration 7.9 version to 8.0, the next week I'm going to migrate a server, but I have many projects on 7.9 and several scripting on it.

I would like to ask you if 7.9 scripting working correctly on 8.1 or I need to do anything else?

Read through the [7.9 to 8.1 upgrade guide](https://docs.inductiveautomation.com/display/DOC81/7.9+to+8.1+Upgrade+Guide), and have a solid backup/rollback strategy in place.

Strongly consider testing each upgrade in isolation on a development system before applying to your production system.
