Let's suposse I have a lot of emails in a private email server. Organized in folders, subfolders, tags, etc.
I want to migrate all this emails (with their current organization) to a new email domain provided by Google and their services. Is there a clean and easy way to achieve this? Or it all depends on the email client I'm currently using?
I could use some tutorials for this but I don't know exactly what to look for...
