Solution
Replace legacy software without stopping operations.
The software works, more or less, but nobody can move it forward anymore and the original vendor is long gone. Replacing it feels enormous. A staged transition is what makes it manageable.
The situation
The status quo is the riskiest option on the table
Aging software collects a quiet tax. Risky changes, no modern backups, no way to connect it to newer tools, and that nagging worry every time the person who knows it takes a vacation.
Replacing it feels daunting because people picture redoing everything at once. That's exactly what to avoid.
The right approach is to audit what exists, rank the components by risk, and replace them one at a time, with the system in service throughout.
Diagnosis
Does your software show these signs?
Technically
- Abandoned or unsupported technology
- No test environment
- Impossible to add features at a reasonable cost
- Data locked in a format that's hard to reach
Organizationally
- The original vendor no longer answers
- One or two people hold all the knowledge
- Procedures exist to work around the software's limits
- A total outage would leave you without a plan B
