Best practices for planning an upgrade

Planning plays crucial role in any Upgrade & Unicode conversion project. So the planning phase should start ahead of time to make sure we included all the items needs to be catered during the project.

Best Practices include:
> Cleaning up modifications and performing selective archiving can reduce the effort of an upgrade considerably.
> Get prepared by doing at least one test upgrade in the early planning phase to identify potential risks, technical challenges and limitations, and cost drivers.
> Perform a technical upgrade first, and then implement new functions or business innovations in subsequent projects.
> Do not underestimate the effort involved in testing. Testing effort will be determined mainly by the need for application adjustment and the functional scope of the upgrade.
> Plan for multiple mock runs (Production like environment) to make sure we don’t face any unexpected issues during production system upgrade
