Merge two Identity Safe accounts

Hi, I currently have a laptop (personal) and a PC (work) both running 360 with there own Identity Safe accounts. I'm replacing both machines and would like to merge the saved logins from both accounts onto my new laptop. Is there a easy way of doing this? I had hoped that I could use the backup function but it deletes the info from the first machine when I try and import the info from the second...

Can somebody help me Please
