I have some queries for anyone who has used Quest Co-existence Manager for Migrating Lotus Notes to Exchange 2013

Case:

Source: Lotus Notes with Notes client v 9.0.  Notes directory and not integrated with AD

Target: Exchange 2013

Co-existence tool: Quest Co-existence Manager

Queries :

Could users have active mailbox in both Exchange and Notes environment?

If yes then how would the mail flow work and would the mailbox and user calendar be in sync?

Could users use Lotus Notes IMAP client to connect to exchange 2013 for mail , Outlook to connect Exchange 2013, and Lotus Notes normal client to connect Domino servers for application access on the same desktop?

Any known issues or risks?

Is this a MS supported and recommended scenario?

I would appreciate if any documentation from Microsoft available for similar cases
