   13. Optionally, start name node only. [[BR]] {{{bin/hadoop-daemon.sh start namenode}}}
[[BR]] This should convert the checkpoint to the new version format.
   14. Optionally, run {{{lsr}}} command: [[BR]] {{{bin/hadoop dfs -lsr / > dfs-v-new-lsr-0.log}}}
[[BR]] and compare with {{{dfs-v-old-lsr-1.log}}}
   15. Start DFS cluster. [[BR]] {{{bin/start-dfs.sh}}}
-  16. Run report command: [[BR]] {{{bin/hadoop dfs -report > dfs-v-new-report-1.log}}}
[[BR]] and compare with {{{dfs-v-old-report-1.log}}} to ensure all data nodes previously belonging
to the cluster are up and running.
+  16. Run report command: [[BR]] {{{bin/hadoop dfsadmin -report > dfs-v-new-report-1.log}}}
[[BR]] and compare with {{{dfs-v-old-report-1.log}}} to ensure all data nodes previously belonging
to the cluster are up and running.
   17. Run {{{lsr}}} command: [[BR]] {{{bin/hadoop dfs -lsr / > dfs-v-new-lsr-1.log}}}
[[BR]] and compare with {{{dfs-v-old-lsr-1.log}}}. These files should be identical unless
the format of {{{lsr}}} reporting or the data structures have changed in the new version.
   18. Run {{{fsck}}} command: [[BR]] {{{bin/hadoop fsck / -files –blocks –locations >
dfs-v-new-fsck-1.log}}} [[BR]] and compare with {{{dfs-v-old-fsck-1.log}}}. These files should
be identical, unless the {{{fsck}}} reporting format has changed in the new version.
