I have deployed Domino 8.0.1 for x32, x64, AIX, Linux so far (Experimental, Research, Production (Linux) servers), and Notes 8.0.1 for x32 (Production Clients).

No problems have occured except the problems which were caused by "officially not supported by IBM" configurations:
- Domino 64-bit + DB2
- Domino 8.0.1 + Quickr 8.0.0.3
- DWA/Lite + Nokia (Symbian)

The next deployments will continue on Development, then Test, followed by Stage, and finally Production servers after a meeting with our consultant next week.
