How to Move message/mail from folder Java IMAP Client

I need to move messsage from an IMAP folder to another IMAP folder (of the same account) via Java.

I work on Gmail and the oauth login.

I use the java imap mail client: i fetch the message with sourceFolder.getMessages() and then I call the method destFolder.appendMessages(sourceFolder.getMessages()) or addMessages: the problem born when the number of the messages to move is too big. I had the to move 8000 mail and the login session expire after several minutes that the procedure has started to add but has not yet finished.

It process about 1 message for second.I use the oauth login

The IMAP MOVE Extension, specified in RFC 6851 from January 2013, introduced:

two new commands, MOVE and UID MOVE, that are used to move messages from one mailbox to another.

It is supported by JavaEE's package com.sun.mail.imap:

MOVE Support

The IMAP MOVE extension (RFC 6851) is supported via the IMAPFolder methods moveMessages and moveUIDMessages.

The normal way to do this is to use server copy and delete. In IMAP syntax, the copy command is tag COPY sequence mailboxname. Like: a000 COPY 1:* INBOX.Saved, would copy all messages to my Saved subfolder.

The method you're doing requires each message to be downloaded then to reupload it.
