Nobody replaces a system that is working.
They replace one that stopped keeping up — usually years after the spreadsheets around it became the real system. Each page below covers one migration: what it costs to stay, what moving actually involves, and the cases where staying is the right call.

- Moving off Excel and spreadsheets
Replacing the spreadsheets that run the business
Every company has them: the file that decides pricing, the tracker that is the real project plan, the sheet that reconciles what two systems disagree about. They work, until the day they do not. - Moving off SAP ECC
SAP ECC: upgrade, replace, or build around
S/4HANA is one answer to end-of-support, not the only one. The right move depends on how much of your ECC estate is standard SAP and how much is twenty years of ABAP nobody wants to re-explain. - Moving off Legacy HIS
Replacing a hospital information system nobody supports
Multi-site hospital groups usually run several HIS platforms at once, one per acquisition, none of them talking. The patient experiences that as repeating their history at every desk.
These are the migrations we have done often enough to write a page about. The others are still work we do, they just do not have a page yet — if yours is not here, talk it through.
