Environment
- EDR: All Supported Versions
Objective
- If there are any custom settings in the EDR Configuration, 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 may be seen. This solution helps understand how to migrate these changes.

1. Before make any changes, backup the original configuration file. For Example:
cp /etc/cb/nginx/conf.d/cb.conf /etc/cb/nginx/conf.d/cb.conf.bakDATE
2. Determine the differences between the files
A. Lines unique to the first file are displayed with a greater than sign (>) at their start, while lines unique to the second file start with a less than sign (<).
diff config.conf config.conf.rpmnew
B. Display two files in columns:
diff -y config.conf config.conf.rpmnew
C. Display context around differences:
diff -c config.conf config.conf.rpmnew
3. Once changes have been migrated over, rename the config.rpmnew file as config.VERSION.changes
mv config.conf.rpmnew config.conf.VERSION.changes
4. Once all .rpmnew changes have been migrated and the files renamed, run the upgrade utility:
/usr/share/cb/cbupgrade

Note that there are significant changes in 5.2 to the nginx configuration files. Read more about it here: 5.2 Nginx Configuration Changes
- If seeing /etc/cb/solr/core_conf/cbevents/conf/solrconfig.xml.template then it's possible to keep the original and rename the .rpmnew file. These changes were made to address performance issues on the server.
- Verify that these are the only differences between the two files:
- solrconfig.xml.template:
- Verify that these are the only differences between the two files:
<int name="maxMergeAtOnce">10</int> <int name="segmentsPerTier">10</int>
- solrconfig.xml.template.rpmnew:
<int name="maxMergeAtOnce">12</int> <int name="segmentsPerTier">24</int>
- Rename the .rpmnew file:
mv /etc/cb/solr/core_conf/cbevents/conf/solrconfig.xml.template.rpmnew /etc/cb/solr/core_conf/cbevents/conf/solrconfig.xml.template.VERSION.default
