[opensuse] Thunderbird, import emails

Hi all, I used to use Thunderbird and now have copied all my email files from on PC into another. Now I would like to import my email to new PC which have Thunderbird again. I have copied my emails files from previous PC into new empty folders and all email have been retrieved successfully. But in my Inbox I have new emails and if I just copy the old file I will loose my new emails. Does anybody know how can I import my email without deleting existing emails in Thunderbird when email file already exists?
