[question] conan install/inspect not working after conan server migration

Hi,

I am having some issues with a conan server migration. I have copied the conan data directory to the new server, package search works but inspect or install fails on the existing packages. A new package on the new server all works as expected, upload, search, inspect, and install.

The old server is using a venv and the data is on a NAS share, inherited so don’t know much about the history but it is time expiring for a couple things so needs to be moved. The new server is not using a venv and a local drive for the conan files.

I have tried a couple different versions v1.9.2 and v1.9.3 but neither seem to work for me.

Search from the client:

Thanks

i copied the venv to the new server, ran the venv server package and checked the functionality. Shut down the venv conan server. Ran conan_server --migrate outside of the venv. Then started the conan_server outside of the venv. Everything is working as expected now. Thanks for pointing me to the older versions not being compatible with the newer versions.

Happy to know it is solved now.

For the future, I would recommend:

• Using the free ArtifactoryCE: It is almost the same effort as running conan_server, but superior in all aspects.
• Take into account that 1.10 introduced revisions, and the layout changes (not sure if you upgraded to 1.9.3 or above 1.10). If you plan to migrate to ArtifactoryCE, the best is to download everything to the client (conan download) and re-upload to the new server.
