Hi Jan,
I want to use n8n for internal purposes of my company, so I will self-host n8n but before that I have read your License file and it mentions that “All EE files are under Enterprise License”. In that case should I have to “REMOVE ALL EE FILES” and build the n8n-custom image and deploy into my server?
Hey @RaviTeja_Karri,
Welcome to the community 
You can self host n8n to use it internally but you can’t bypass the requirements to enable or access features behind the enterprise license.
So, in that case I don’t need to remove EE files right?
And Can I change the UI of n8n?
Hey @RaviTeja_Karri,
There is no need to remove the files and it will probably cause issues if you did, Typically changing the UI of n8n falls under the embed option (White labelling | n8n Docs). If you are running your own n8n instance just for internal purposes it may be ok, I would drop an email to [email protected] for further clarification.
