We are planning an upgrade our mail servers to 8.5. We must save on disk space and think that implementing DAOS must help us. However, most clients are 6.5.x or 7.0.x. From your experience, if I convert mail databases to ODS51 and enable DAOS on 8.5 servers, will older clients be able to access their mail without much change? What issues shall I expect?
Is it a good idea at all?
Thank you.
