Exporting Index from Unstable to Stable

I have two different VPSs running YaCy:
The first was done using Yunohost and is so unstable it keeps crashing.
The second is directly using the docker container from YaCy’s website.

What is wild about this is that the unstable yunohost version is NEWER.

Unstable crashing using Yunohost:
1.924/10069

Stable using Docker container:
yacy_v1.940_202407241507_d181b9e89

I’m looking to export the index database and transfer it, but it’s not even letting me do the export or data dump. It just keeps forwarding to the Yunohost login page in an infinite loop.

Can I just literally copy the index files using rsync ?
Which folder(s) is it in?

Hi,
you can copy whole DATA dir. But said works only for switching from version of solr (bundled into yacy) to one number higher (e.g. 8 to 9).

1.924 is actually older than 1.940.

1.940 yacy uses solr 9
1.930 yacy uses solr 8
afaik
the other versions, i don’t remember, but table in the docs would be helpful

I see, so you’re saying it can’t be exported due to the version differences being too great?

No, I mean when moving DATA directory, which is the easiest way.

Exporting/importing should work accross the versions. Did you check the log for error messages?

If the imported data occupied some space: try to examine the DATA directory, where the data should be imported.
You can try (on unix) du -hs DIRNAME to examine the size of particular dirs.

I got no clue nor experience, so this is the way to debug…
