01 / Overview
Overview
Migration is where implementations go wrong
Moving accounting data is not a file conversion. Ledgers have to map to a new chart of accounts, inventory masters have to survive with their units and valuations intact, and the opening balances you start with have to agree with the closing position you left behind.
When that reconciliation is skipped, nobody notices immediately. It surfaces months later, when a trial balance does not tie or an auditor asks how a figure was derived - and by then there is a year of transactions sitting on top of the discrepancy.
BlackCat handles master and transaction data migration with full data integrity checks, and reconciles opening balances against your previous system before go-live.

03 / Problems
What it solves
What we check for
Opening balances that do not agree
Reconciliation against your prior closing position, before the first new voucher is posted.
Ledgers mapped to the wrong group
Chart-of-accounts mapping reviewed so reports classify correctly from day one.
Inventory that loses its valuation
Stock masters, units and valuations carried across intact rather than re-keyed.
Orphaned or duplicated masters
Duplicate customers and suppliers cleaned up during migration rather than inherited.

07 / FAQ
FAQ
Frequently asked questions
Can you migrate existing Tally data?
Yes. We migrate from Tally ERP 9, older Tally versions, Excel, QuickBooks, Zoho Books and other ERPs with full data integrity checks.
Will our opening balances be correct?
Opening balance and master-data migration is part of the process, and balances are reconciled against your previous system before go-live.
How long does migration take?
Migration runs as part of implementation. Standard setups go live in 48-72 hours; complex multi-branch or custom implementations typically complete within 2-3 weeks.
Do we lose our transaction history?
No. Master and transaction data migration is included, so prior periods remain available in TallyPrime.
