Are you planning to switch from Exchange to Lotus Notes? Remember, both these email clients support different file formats, i.e. Exchange Server creates EDB file and Lotus Notes creates NSF file. So if you're migrating your data from Exchange to Lotus Notes, you must convert EDB to NSF format. Generally, email conversion is only possible through a 3rd party tool. But if you're looking for a free solution, you should use the nUpgrade utility, a part of Notes migration tools. This utility will help you migrate from Exchange to Notes without using any 3rd party paid tool. Refer to this article for complete information - Exchange to Notes Migration – Export Emails to Lotus Notes

I hope the shared information would be helpful here. 

Thanks.
