Top 20 application issues in Windows 7 migrations
July 13, 2011 Leave a comment
Applications are the most essential pieces of the jigsaw in an operating system migration / upgrade project. Your business or users will not accept having malfunctioning or broken applications due to you replacing the operating system no matter how cutting edge the OS is, or even if there is a reduction in the cost of desktop and application management post-migration. Most business processes are dependent on applications and the migration of these applications have to be carefully planned in order to prevent unhappy and dissatisfied customers.
Here is a list of the common application issues encountered during Windows 7 migrations:
- Applications with 32 bit drivers (if migrating to the 64-bit version of Windows 7)
- Applications with licensing issues (licenses tied to specific hardware)
- Applications with dependencies on IE6 or IE7
- Applications without installation instructions
- Applications without vendor installation source files
- Multiple versions of the same application
- Applications used across multiple business units without any ownership
- Applications with launch conditions preventing installation on Windows 7
- Applications provided by vendors who are now out of business
- Applications not used in the last 90 days, 180 days or 365 days day
- Multiple applications serving the same business processes
- Applications using the old help file format (.hlp)
- Inadequate information on application dependencies and prerequisites
- Hard coded paths to deprecated locations
- Applications with 16-bit components (if migrating to the 64-bit version of Windows 7)
- Out of support applications
- Compatibility with Microsoft Office or similar productivity suites e.g. Google Apps, Zoho, Open Office etc.
- Applications dependent on Microsoft .net framework 1.1 (if migrating to the 64-bit version of Windows 7)
- Multiple Oracle clients
