Before you start any upgrade or migration project, you need to have a clear picture of your application portfolio, infrastructure, business processes and software, and know what you have versus what you need. Not always a simple thing to achieve with businesses typically suffering from severe application bloat.
Application Audit & Rationalisation enables you to audit your application estate then review and rationalise applications ahead of performing other activities, so you only take forward applications you still need. It is also a good practice that helps to minimise vulnerabilities on your devices and to save money.
