Migration from open source edition to enterprise edition

I have a TTS installed on premise with open source edition.
My project is growing and in the near future, probably, I will need to scale up the stack to support more end-node and to balance the load over the stack.
So i will need to migrate from open source to enterprise edition because the open source does not support scaling.
Is this migration possible?
If yes, is it possible only changing the configuration files of open source installation or do I have to create the new installation based on enterprise edition and then migrate all the devices to the new installation?

Thanks

You need to contact TTI directly for this - staff members drop by occasionally but mostly it’s non-staff volunteers on the forum.
