Why It Matters
Why App Migration Needs a Specialist Approach
App migration at ERPHUBs covers re-platforming native apps to Flutter or React Native, web-to-mobile conversions, PWAs, legacy-to-cloud moves, cloud database migration, ERP/CRM migration and app store transfers.

Industry Bottlenecks
What Stalls App Migration Projects, and How We Design the Fix
Downtime
The bottleneck. Users lose access.
How we design it. Phased cutover and parallel running.
Target result: Minutes typical cut-over downtime
Lost reviews and ranking
The bottleneck. Store transfers reset history.
How we design it. Transfer-safe processes and listing preservation.
Target result: 100% feature parity checked
Unknown legacy logic
The bottleneck. Nobody documents old code.
How we design it. Code archaeology and test capture before moving.
Target result: Rollback always ready
Migration Risk Control
Migration Risks and How We Remove Them
Migrations fail in predictable ways. We plan for each one before the first record moves.
Data loss or corruption
The risk. Records are altered or dropped during transfer.
Our safeguard. Checksums, record counts and sampled comparisons at every trial load.
Extended downtime
The risk. Users locked out during the switch.
Our safeguard. Continuous replication and a rehearsed, time-boxed cut-over.
Feature regressions
The risk. Behaviour differs from the old app.
Our safeguard. Automated regression suite and side-by-side user acceptance tests.
Lost reviews and users
The risk. Store changes reset ratings or break updates.
Our safeguard. Same bundle IDs, transfer-safe processes and staged rollouts.
Security gaps
The risk. New environment is configured loosely.
Our safeguard. Hardened landing zone, secrets management and access reviews.
Cost overruns
The risk. Cloud or licence costs exceed forecasts.
Our safeguard. Right-sizing, budgets and alerts from the first week.
Sign-off Checklist
How We Prove the App Migration Worked
Nothing goes live on trust. Each item below is checked, recorded and signed off with you before cut-over.
- Record counts match between source and target for every table
- Checksums and sampled records compared for critical entities
- All integrations and webhooks re-tested end to end
- User accounts, roles and permissions verified
- Performance matches or beats the old system under load
- Backup and restore tested on the new environment
How We Deliver
A Five-Step Delivery Path

- 2PlanTarget architecture, mapping and rollback plan.
- 3MigrateStaged moves with automated checks.
- 4ValidateReconciliation and parallel run.
- 5Cut overSwitch, monitor and retire the old system.
Standards We Build To
Quality, Security and Compliance in App Migration
Record-level reconciliation
Counts, checksums and samples compared between old and new.
Rehearsed cut-over
At least one full dress rehearsal before go-live.
Security and compliance
Encrypted transfer, access control and audit logs.
User continuity
Accounts, sessions and settings carried across.
Planning
What Affects Timeline and Cost in App Migration
Typically 4 to 16 weeks depending on size, data volume and downtime limits.
Size and age of the system
Older, larger systems need deeper discovery.
Data volume
Large datasets need staged or replicated loads.
Downtime tolerance
Zero-downtime plans add engineering effort.
Third-party dependencies
Every library and integration must be replaced or re-tested.
Engagement Models
Ways to Work With ERPHUBs
Fixed-scope project
A clear scope, timeline and price for well-defined work.
Dedicated team
A named squad that works as part of your team month to month.
Support retainer
Ongoing fixes, updates and monitoring after launch.
Tools and Technology
How We Build App Migration
Assessment tooling
Code, data and dependency scans that size the work before quoting.
Data migration
Scripted extraction, mapping and validation with repeatable dry runs.
Parallel testing
Old and new systems tested against the same cases and datasets.
Cut-over controls
Freeze windows, rollback plans and live monitoring on go-live day.
Success Metrics
How We Measure App Migration Results
We agree measurable targets up front and report against them.
Data reconciliation
Record counts and balances matched between old and new systems.
Downtime
Planned cut-over windows measured in minutes where possible.
Defects after go-live
Open critical issues at day 7 and day 30.
User adoption
Logins and task completion compared with the old system.
Before You Decide
Questions to Settle Before Starting App Migration
Will users lose data or access?
Dry runs and reconciliation reports prove nothing is lost before cut-over.
How long will we be offline?
We plan the shortest safe window and rehearse it.
What if something goes wrong?
A tested rollback path is part of every migration plan.
Do you handle store and account details?
Yes, including bundle IDs, certificates and compliance forms.
After Launch
Support, Maintenance and Handover
Monitoring and fixes
Uptime, errors and performance watched, with fixes under agreed response times.
Updates and security
Dependencies, platforms and security patches kept current.
Enhancements
A monthly pool of hours for improvements, prioritised with you.
Training and handover
Documentation, recordings and sessions so your team stays independent.

App Migration, Answered
Can you migrate with zero downtime?
For many systems, yes, using parallel runs and phased switching.
Do you document the old system?
Yes, we capture behaviour and data models first.
Do you transfer app store accounts?
Yes, with ownership and compliance checks.
How much does App Migration development cost?
Cost depends on scope, integrations, compliance needs and the number of users or pages. After a short discovery we give a fixed or phased quote with clear milestones, so you can compare it with other options.
How long does App Migration development take?
Typically 4 to 16 weeks depending on size, data volume and downtime limits.
What support do you provide after App Migration development goes live?
We offer support retainers covering fixes, updates, monitoring and enhancements, plus a handover with documentation and training so your team is never locked in.

Africa
App Migration Development: what Africa teams should plan for
Moving to Zoho from another system in Africa means mapping tax codes, currency and opening balances correctly the first time, then switching over between filing deadlines.
Cutover timed to your calendar
We avoid the busy filing windows: Ongoing: Check Kenya eTIMS and Egypt e-invoice onboarding; South Africa: month after period end: VAT201 via SARS eFiling.
VAT (country-specific) code mapping
Existing tax codes are matched to VAT (country-specific) (ZA 15%, NG 7.5%, KE 16%, EG 14% standard) in the Zoho Books (South Africa and Kenya editions where available).
Where your data lives
Your Zoho account is created on the Nearest data centre (EU/US/IN) per customer need (zoho.com).
Moves we see most here
Typical sources in Africa: Sage / Pastel, QuickBooks, Tally, Excel.
Yes. The Africa team configures it with the Zoho Books (South Africa and Kenya editions where available), USD and VAT (country-specific), and supports it Mon-Fri 09:00-18:00 CAT.
Zoho accounts for Africa use the Nearest data centre (EU/US/IN) per customer need (zoho.com). We confirm the data centre with you before any migration or integration starts.
