Running ERP upgrades without stopping the business

Key points

• Most upgrade problems come from untested customisations.
• A rehearsed cut-over is the best protection for go-live.
• Finance and operations users should test their own processes.

Preparing for the upgrade

List every customisation and integration, decide which can be retired, and test the rest against the new version early.

Cut-over without surprises

Rehearse the cut-over at least once with real data volumes, agree go or no-go criteria in advance, and keep support close at hand in the first weeks.
