Data Migration - Options

Posted on by MD-28081349-0 6
Hello,
In my experience, the best practice for Business Central implementation is to Migrate GL balances and open transactions (Sales, Purchasing etc.).  My client is going live mid-year July and they want to migrate GL journals and Subledger transactions for Jan-June periods.  They have a very old finance system and the new BC system will have a different chart of accounts, dimensions and other linked data.   Has anyone done an implementation taking detailed transactions over (not just GL balances)? appreciate your advice, Pros, Cons and risks ? Thanks, B

    Hi, By default, Business Central customers can use up to 80 GB plus an allowance per licensed Essentials or Premium user of database storage capacity. And table and database sizes have a significant impact on the performance of Business Central online. So GL balances and open transactions are the minimum data to use the new system, which is the most recommended approach.
    However, some customers want to query the data of the old system in the new system. Although it is not recommended, it can be integrated into BC. But customers may need to pay for capacity . . . and if the data is too large, performance may be affected.
     
    Hope this can give you some hints.
    Thanks.

    Thank you Zhu. Storage capacity is indeed a significant factor in our decision.  We weren't aware of the limitation.
     
    Have you experience of migrating in-detail the GL journals, and subledger data?  If so, advice on how to do this, how to ensure the BC figures reconcile to the legacy system, and how to minimize the manual reconciliation etc. ?
