Preparation needed when change the version of Hadoop

Hi everyone

We have implemented a cluster with Apache version 1.0.4
Due to some corporation issues, we need to change the version to Cloudera
CDH 4.2.0.
1.How to uninstall the current Hadoop without any unnecessary files leave
behind?
2.Any preparation for this change？
