we want to migrate data from an open source Atlas 1.2.0 to an Atlas in version 2.1.0 included in our Cloudera CDP 7.1.7 cluster.
In addition, the versions of solr and hbase of the source cluster are Solr 5.5.1 and Hbase 1.1.0.
To migrate Atlas data, is it sufficient to perform a backup of the hbase tables from the source hadoop cluster and a restore on the target CDP cluster hbase?
Is it necessary to backup and restore Solr collections as well? I know that the Solr 5.5.1 of the source cluster is not compatible with the Solr 8.4.1 of the target cdp cluster, so if possible I would like to avoid the export/import of the collections and perform an indexing of solr after the migration of the Hbase tables . Is this the correct procedure to follow?
Thanks in advance.
