V1 Dovecot POP3 index migrate to V3

[Umut Arus]

Hi,

I've very old Dovecot version so I'm trying to migrate new disk and current
version of dovecot. But POP3 accounts have "version 1"
.INBOX/dovecot-uidlist files so clients download the messages again.

How can achieve not to download to mailbox after copy to new disk? Is there
any script or something to migrate index v1 to v3?

thanks for your suggestions.
