Solr

The AM2CM tool does not migrate Ambari Infra Solr configuration and data to Cloudera Manager. However, it adds a new Solr service. To take a backup, perform the following steps after the transition.

Create a local directory for backups first:
```
mkdir -p [backup_dir]
```

Execute the following commands on the hosts where Solr is installed.

mv /etc/alternatives/solr-conf [backup_dir]/solr-confhdp
mv /etc/alternatives/hue-conf [backup_dir]/hue-confhdp
mv /etc/alternatives/hbase-solr-conf [backup_dir]/hbase-solr-confhdp

For RHEL:

mv /var/lib/alternatives/solr-conf [backup_dir]/solr-confhdp

For Ubuntu:

mv /var/lib/dpkg/alternatives [backup_dir]/solr-confhdp

For Sles:

mv /var/lib/rpm/alternatives [backup_dir]/solr-confhdp
