Legacy is not the enemy
The system everyone wants to replace is usually the one encoding twenty years of hard-won business rules. Modernise around it before you modernise it.
Every transformation programme meets a system that everyone agrees must go. It is slow, poorly documented, and maintained by two people. It is also, almost always, the only place where the organisation's actual business rules are written down.
Replacing it wholesale means re-deriving those rules under deadline pressure. That is where transformation programmes fail — not on technology, but on the quiet accumulated logic nobody remembered to specify.
The alternative is to modernise around it. Put an integration layer in front of the legacy system. Move new capability into services that talk to that layer. Instrument it, so you learn what is actually used. Then retire it in pieces, each one small enough to verify.
It is less dramatic than a rewrite and considerably more likely to still be running in three years.
