The "Hbase/HowToMigrate" page has been changed by DaveLatham: http://wiki.apache.org/hadoop/Hbase/HowToMigrate?action=3Ddiff&rev1=3D37&re= v2=3D38 In general, performing a HBase migration will consist of the following st= eps: = * Shut down the old instance of HBase. - * If necessary, upgrade the underlying version of Hadoop to the version = required by the new instance of HBase. Refer to the [[http://wiki.apache.o= rg/hadoop/Hadoop%20Upgrade|Hadoop Upgrade]] page. + * If necessary, upgrade the underlying version of Hadoop to the version = required by the new instance of HBase. Refer to the [[http://wiki.apache.o= rg/hadoop/Hadoop_Upgrade|Hadoop Upgrade]] page. * Optionally backup your hbase.rootdir. * Download and configure the new instance of HBase. Make sure you confi= gure the ''hbase.rootdir'' of the new instance to be the same as that from = the old instance. * From the new instance of HBase, perform the HBase migration. Run {{{{= $HBASE_HOME}/bin/hbase migrate}}} for usage. See the version-specific note= s below for more specific information on this process.
