All Versions of Cb Response
Topic
If you have a custom datastore directory in your Cb Response Configuration, you will likely see a message while running /usr/share/cb/cbupgrade stating that .rpmnew files have been created and these settings need to be moved over before the upgrade can complete. This solution helps understand how to migrate these changes.
These .rpmnew files might need to be migrated on the minion:
/etc/cb/redis.conf /etc/cb/datastore/tomcat6.conf /etc/cb/nginx/cb-nginx.conf /etc/cb/nginx/conf.d/cb.conf /etc/cb/solr/tomcat6.conf |
These .rpmnew files might need to be migrated on the master:
/etc/cb/redis.conf /etc/cb/nginx/cb-nginx.conf /etc/cb/nginx/conf.d/cb.conf |
Warning: This guide details general configuration changes that needed to be made and your process may differ. Please confirm that no additional changes need to be made by comparing the two files.
