Risk assessment
What should be checked before touching the old installation?
Record the application version, device condition, last successful use, available backup files and business records that can still be opened or exported. Stop making unnecessary changes while the recovery path is assessed.
Backup options
Which records should be preserved?
Use the application's available backup or export tools where they still work, and separately preserve readable business records. Only use formats actually available in that installation.
- Application-created backup files and their original folder context.
- Readable invoice, party, item, stock and balance exports where available.
- Sample printed or PDF invoices used to verify layouts and totals.
- A full copy of the relevant device data made by a competent technician when needed.
Device preparation
How should the computer be prepared?
Use reputable security software, preserve suspicious installers for professional analysis only when necessary, update the operating system safely and avoid signing into sensitive accounts until the device is considered trustworthy.
Controlled restoration
How should the original installation be tested?
Install through the official route on a controlled device or profile, activate under documented terms and attempt restoration without deleting the source environment.
- 1
Create and label the source backup with date, version and device.
- 2
Install the official build separately where possible.
- 3
Test the supported restoration or import route.
- 4
Compare record counts and representative historical transactions.
- 5
Approve cutover only after the owner signs off the verification list.
Financial verification
What must be checked before the business switches?
Verify opening and closing balances, customer and supplier totals, item quantities, tax or discount treatment used by the business, invoice numbering and recent sales or purchase documents.
- Parties and outstanding balances match an independent record.
- Key inventory quantities and valuations are reviewed.
- Recent invoices reopen and print correctly.
- A fresh backup from the original installation can be created and located.
Parallel run
Should the old and new systems run together temporarily?
For higher-risk migrations, a short controlled parallel check can help compare totals. Avoid uncontrolled double entry: define which system is the live source and who reconciles differences each day.
Professional help
When is specialist migration assistance needed?
Seek help when the backup cannot be opened, the device shows malware signs, financial totals disagree, the business has long history or multiple branches, or downtime would materially affect operations.
