Hello

I’ve decide to upgrade my ruby ee from 1.8.6 to 1.8.7 on debian. I’ve  
copied all gems from /opt/ruby-enterprise/ to new location but  
unfortunatelly it doesnt work, do I’ve to reinstall all gems?

You could copy the gems directory from your 1.8.6 installation to the  
1.8.7 installation (if you haven’t uninstalled the old one yet). But  
otherwise, I believe you will have to reinstall any gems you are using.

Any gems that require native extensions will probably not work just by  
copying them, you will have to reinstall them.

If you still have your 1.8.6 install, you can see a list of installed  
gems by doing ‘gem list --local’, which should help you in  
reinstalling them on the new version.

It is recommended since gems with binary extensions will be trying to  
link to a different Ruby shared object that could expose a different  
ABI (in theory).

You can simply do the following:

gem install rubygems\_snapshot

then export the list of gems you currently have and import it on your  
newer installation.
