Our Journey from Microsoft Dynamics GP to the Business Central Cloud Part 4: Go-Live WeekThis series has been focused on our migration from Dynamics GP to Dynamics 365 Business Central. We’ve discussed the challenges we were facing and a desire to eat our own “dog food”, our plan for adopting cloud-first technologies, and our actual implementation activities leading up to our Business Central go-live.

Now go-live week is here, the first week of January. Part of our pre-go-live implementation activities included:

  • Bringing in our G/L transactions to Business Central up through March 2020
  • Reconciling the financial reporting in BC with our GP financial reports up through March 2020
  • Populating customers and vendors in BC
    • Once we did that, we had to perform dual maintenance in GP and BC as new customers and vendors were onboarded
  • Tested all business processes that touched BC (invoicing, cash receipts, G/L entries, checkbook reconciliation, etc.)

At this point, Business Central and GP were in sync from a data perspective through March of 2020.

These activities enabled us so that on 1/1/2021 we would:

  • Suspend all posting activities in GP
  • Begin transacting in BC (this was mainly related to sales invoicing – we just left them as unposted while we completed the rest of the activities)
  • Export out the G/L transactions from GP and import them into BC
    • This was relatively easy by using a SQL script to get the data out of GP, doing a little “massaging” on that data in Excel to account for some restructuring we did (we used an Excel VBA macro for this, then using the copy/paste functionality in Business Central.
  • Exporting uncleared bank transactions from GP and importing them into BC
  • Exporting open A/R and A/P balances from GP and importing them into BC
    • For the bank transactions and A/R and A/P imports, we used BC configuration packages developed by our implementation consultant
  • Reconcile monthly financial reports in BC with our GP financial reports from April through December (this was mainly just ensuring the G/L account category totals matched in both systems)

Overall, this process took about 3 business days. By business day 4, we were up and running completely in BC. The key to our success was having a knowledgeable consultant that had done this before with several other customers. This give us confidence in our ability to be successful prior to our Business Central go-live, the actual activities were just about checking items off the to-do list.

Payroll Go-Live

You might be thinking...“Wait – you didn’t talk about your payroll implementation. I thought you implemented Payroll NOW as part of this process as well.”

We did indeed implement Payroll NOW in Business Central after migrating from GP payroll. While there are a few dependencies on core BC functionality (G/L and vendors), most of the Payroll NOW implementation can be completed in a bubble of sorts. Our HR Manager completed our Payroll NOW implementation with some help from our knowledgeable implementation team. Most of these setups were completed before go-live. Given that we were doing a 1/1 implementation, we didn’t need to bring over any historical transactions. Also, we had a couple weeks to finalize our Payroll NOW implementation in January because of how the pay periods fell. Honestly, the Payroll NOW implementation was a breeze.
