How can I create / access a Sandbox on the cloud for an old version of Business Central, preferably version 14 but I’ll take anything close to that. My dev PC doesn’t have the resources to run Docker or Hyper-V.
You cannot run old versions in a Sandbox Cloud… the only method is to use a Docker, if your PC doesn’t have enought resources, try in Azure: Run Docker containers with Azure Container Instances - Training | Microsoft Learn, but it has a cost.
