Millennium Compliance Carol P. Conway offers a few tips that are equally applicable whether your firm does its Y2K upgrading in-house or via outsourcing. Some software is more vulnerable. Proprietary software written specifically for a company or industry is particularly prone to Y2K complications. This is especially true if the software was written prior to 1993. In general, DOS-based systems are at higher risk than Windows environments.
Some software is less vulnerable.
Quickbooks, Office 97, and new versions of Netware and Windows NT that run on Pentium computers are usually already compliant or else are readily upgradeable. However, results can vary widely and even new computers need to be tested. Use a parallel system for testing modifications, especially for proprietary software. Avoid the risk of corrupting your current system. Copy all relevant files and programs to a separate, parallel environment specifically for testing.
