Why upgrade to v8.0 (old LTS) and not v8.4 (current LTS)?

Especially given that end-of-support is only 18-months from now (April 2026) … when end-of-support of v5.7 is what drive them to upgrade in the first place.

Since direct upgrade to 8.4 isn't supported. They got to go to 8.0 first.

Also: 8.0 is old and most issues have been found. 8.4 probably has more unknowns.
