Migrate OSS 1.9.9 to 3.X

Hello,

I currently have a Nexus OSS 1.9.2.2
I want to migrate to Nexus 3.X

The documentation i found (https://support.sonatype.com/hc/en-us/articles/213464338-Nexus-Repository-2-Upgrade-and-Compatibility-Notes) explains that it’s possible to migrate from1.x to “any greater version up to 2.7.2 *”.
So I will have to do at least 2 migrations, correct ? (1.9.2.2 → 2.7.2 → 3.X)
But i can’t find any source for the 2.7.X

Any ideas ?

Thanks in advance,
Regards
