I’ve seen several posts here and I’m not sure what to believe. Exclusing plugins I’m wondering if 1.13 now supports 6.8. Meaning if someone is running 6.8 core software, can they upgrade to 1.13? Thanks in advance.
Wait a minute. OpenSearch 1.13 isn’t a thing! Are you talking about Open Distro?
Yes. Sorry. Open Distro
In ES, any version is also compatible with one ‘major’ version back, so yeah, 6.x should be able to work with to 7.x (Open Distro 1.13 uses 7.x core). ES doesn’t use strict semver, so there may be gotchas around corner cases, especially for plugins.
