If you want to migrate Zimbra to Exchange Server then I suggest third-party software like Zimbra to Exchange Migration tool.

The software migrates Zimbra to Several file formats such as PST, MBOX, EML, EMLX, HTML, PDF, NSF, OLM, and etc. This software has no file size limitation to migrate an oversized Zimbra file to Exchange Server.
