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?

1. Debian GNU/Linux 7
2. I do not know exactly, most likely zip. Can I somehow find out for sure?

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./
