I have been running the community edition for a couple of years on C# and Java source code. My company know wants to upgrade for scanning C/C++ source code.
Postgres 9.6 database.
So we have been on CE version 7. upgrade to CE 7.9.4 without a problem. Then it failed to CE 8.5.1. Twice.
So I went from CE 7.9.4 => Dev 8.0 => Dev 8.5.1 failed
Next Dev 8.0 => Dev 8.1 => Dev 8.5.1 failed
So I decided to stay on version 8.1. Our database have 45 millions line of code. Our continuous integration builds was submitting results. Now we are moving the Development edition, the CI builds will be disable. Now, I have deleted all the projects to get below 1 million line of code to use the trial version develop.
