Trigent Software-Windows to Linux Migration

The project was conceptualized to reduce the CAL and server licensing costs

and high maintenance and administration effort required on Windows. On migrating

the FTP server from Windows to Linux, the company was able to provide high

availability of FTP services both internally and to clients. Similarly,

migrating the DHCP Server from Windows to Linux enabled the organization to

eliminate the CAL and server licensing of Windows 2000 Server. Migrating VSS

(Visual Source Safe) from Windows to Linux CVS allowed the organization to do

away with the CAL and server licensing for non-Microsoft technologies such as

Java and PHP.

The company also realized that some users of Microsoft Office 2000 and 2003

did not require the capabilities of Microsoft Exchange. These users were moved

to Novell Open Office, which was very stable, and their mail clients were also

moved from Microsoft Outlook to Mozilla Thunderbird or Outlook Express as per

their needs. Trigent's DHCP server was initially on Windows 2000 Server, where

even after configuring the Pool and Scope, IP conflicts occurred regularly on

the network and the MAC to IP binding did not work in some cases. The DHCP

server was migrated to Fedora Core 5, after which the company was able to

reserve all IPs and MACs as they could on Windows.
