C/AL → AL conversion
We rewrite your C/AL code in AL and deliver it as a PTE app (Per-Tenant Extension). Business Central can then be updated without your customisations breaking.
01 · Cloud Migration
From Navision, NAV, C5 or on-prem BC to Business Central online. Data, history and customisations come along.
- Data and history moved across

02 · Data history
30 years with Navision — through every generation
Old accounting history is often the first thing dropped in a migration. With us, it is your choice. If you want all your historical data in the new solution, we move it — however far back it goes.
That is why we run our own conversion servers on Proxmox. On them we can run every version of Windows client and server, all the way back to Windows 95, and pull the data out of them.
Navigator 3.56 too
We upgrade the database step by step through up to 6–7 versions, so the accounting data is 100% valid at the other end. Both native NAV and MS SQL.
Proxmox in-house
Our own conversion servers. Your data never leaves our environment along the way.
Legacy OS
Windows 95, 3.11 and NT, DOS, OS/2 and Novell. We can start the old systems up and pull the data out.
Database formats
Native NAV database and MS SQL. We handle both.
03 · Future-proofing
Code, reports and customisations
If you have spent years on customisations in NAV, they should not be thrown away. We move them across.
Reports upgraded to RDLC
Your own reports are upgraded to RDLC. The design your users know stays the same.
Result: Standard Business Central plus one PTE app with your customisations.
04 · The process
Four steps to go-live
You approve each step before we take the next. And it is the same people all the way.
01
Conversion report and sandbox
We write a conversion report on what is moved and how, and set up sandboxes with your real data.
02
Testing on your own data
You test in the sandbox: customers, items, entries, balances. No demo data.
03
Training on your own data
We train your users — on site or online — on your own converted data. We only stop when they can manage on their own.
04
Go-live
Once you have approved the solution, including your PTE app with the customisations, we run the final data migration and go live.
"We never work with fictional demo data."
Testing and training take place in your own converted accounting data. So you know what you are getting before you go live.
05 · Infrastructure
Microsoft 365 & hybrid cloud
We also move the rest of your local Microsoft environment to the cloud: files, SharePoint and email.
File servers
Local file servers are moved to SharePoint Online and OneDrive. Permissions come along.
SharePoint
SharePoint On-Premises is moved to SharePoint Online: sites, documents and workflows.
Exchange
Local Exchange is moved to Exchange Online with the full mailbox history.
Hybrid connections during the transition
We set up hybrid connections between your local Active Directory and Azure, and between local Exchange and Exchange Online. Your users can keep working while we move.
