-- Upgrading our connectivity software from RDC/Terminal Server to Citrix ICA;

-- Deploying server virtualization and SAN (storage area network) technology;

-- Upgrading Windows Server, SQL Server, and triCerat (software that supports printing across the WAN);

-- Buying new scanning software to interface with the upgraded medical records app.

OK, there were issues. Our CIO had no experience with Citrix ICA ' or server virtualization ' or SANs. But we figured if we moved through this process one step at a time, everything would be fine.
