Old system notes

Notes on replacing old systems without breaking operations.

Notes for organisations that depend on an old database, old admin system, or vendor setup that is difficult to understand or change.

Reader: Owners, CFOs, IT managers, and administrators responsible for old systems.
Risk: Hidden problems in users, reports, exports, permissions, backups, and vendors.
Output: Questions that protect daily work before replacement starts.

Questions

Questions to ask before choosing a system path.

These are simple checks for deciding what should be built, fixed, secured, or left alone for now.

Who uses the old system every day?

Which reports and exports depend on it?

Are backups working and tested?

Who has admin or vendor access?

What must keep working during replacement?

Guides

The guides are written for real operating situations: ordering, field work, old databases, reports, records, and approvals.
