It looks like Nexus Repo 3 is not able to contact Repo 2. Check the nexus.log for more information.

Hi Rich,

Thank you for direction.
Yes, there is error “No route to host (Host unreachable)”, Please find the attached logs.

both the dockers running same IP address. Only difference is port numbers.

How we could solve this issue?

Thanks,
Vijay

“No route to host” means a network connection can’t be established. Ensure that the two hosts can reach each other via the network.

Hi Rich,

After resolve the issue for host connection, Got the following error “Cannot upgrade nexus/OSS/2.14.5-02 to nexus/OSS/3.20.1-01, Nexus Repository Manager 2.14.13-01 or higher is required”

Seems like need to upgrade first to Nexus Repository Manager 2.14.13-01 then upgrade to nexus/OSS/3.20.1-01

Can you able to share the some link or steps to upgrade from OSS 2.14.5-02 to 2.14.13-01 ?

It is not clear what your setup is… are these two different docker images, or are they both in the same?

But basically… if both instances are on the same machine, and on the same disk, use the hard linking method. That is the fastest by far.

If they are on the same machine, but on different disk volumes use file copy.

If they are on different machines you’ll need to use http transfer. That will be a lot slower though.
