Hello. Please tell me, if when updating the version of the elastic, it does not matter to me that the old index is saved - can I just delete the old version and install the new one?
What OS are you on and how did you install it - a deb/rpm/windows installer, or a zip?
- Debian GNU/Linux 7
- I do not know exactly, most likely zip. Can I somehow find out for sure?
dpkg -l|grep -i elasticsearch.
ii elasticsearch 1.0.1 all Open Source, Distributed, RESTful Search Engine
Wow, that's super old! In this case you can't just do an
apt-get upgrade, as 1.X isn't compatible with any of the latest versions.
Ideally, you would create a new 6.X cluster and then run a reindex from the old cluster to the new one./
Thank you, I'll do it
