Upgrade JasperServer 4. to 7.8 or higher

[dav2]

Hi everyone,
I have a question.
I would need to upgrade a version 4 jasperserver to 7.8 or higher.
Can you tell me what the correct steps are?

I read that you need to update it to version 6 first, then to 7 and then to 8 (eventually)... but I can't find version 6 downloadable anymore.

Not finding version 6, I directly tried to install 7.8 and launched the export on the old server with the command:
bash js-export.sh --everything --output-zip /tmp/all.zip

and then import onto the new one:
bash js-import.sh --input-zip /tmp/all.zip --update

But I lost the launch parameters of the report schedules.

I use Linux but I can use Windows.

Can you help me?
