Using V4.81 for 3 separate mailboxes for 20 plus years and I'm thinking of converting them from POP to IMAP and I'm wondering if there's a simple way to do this?

All three of these mailboxes have hundreds of folders and thousands of emails and I'm hoping there might be a simple way to switch?

Is there a tutorial for this that someone could point me to?

If it's very complicated, is there a way to view old emails in the POP account and just start to use new emails in an IMAP account for one of the users?

Thanks!!!!

There isn't such thing as conversion from POP3 to IMAP, the protocols are very different. POP3 downloads messages and stores them locally. IMAP displays the messages that are on the host server. It does not have a download mechanism, although copying messages to a local mailstore is possible.

When you create an IMAP profile in Pegasus Mail, that connection appears in the Folders list as another mailbox. That makes sense since its data is not local as represented by "My mailbox" but is in a different physical location, the host server.

Disabling a POP3 host will stop downloads from that account. Doing so will not affect existing data in "My mailbox". Creating an IMAP profile for that account will then start displaying the data that is in its host server mailbox.
