Restore old pop mail withount affecting current imap

OK I used to use POP and did backups of all my emclient folders and settings. I’ve been using IMAP for past 3 years so my question is:
If I restore my POP settings and data so I can view old correspondence, will my email for the past 3 years be transferred from servers to my emclient app? I don’t want that to happen!! Is there a process I can follow to limit my POP mail to only the Restore without receiving new mail? Thanks
