I did upgrade from confluence 5.0.3 to 5.7 in my local (using 32-bit windows installer) and now I am not able to run the server, it's not working. I was able to upgrade successfully to 5.0.3 from 3.4.9, using the following path:
3.4.9 -> 3.5.17 -> 4.3.0 -> 5.0.3
Can we not directly upgrade to 5.7 from 5.0.3 and if not then, what should I do now? Do I have to do everything fro the start?
