When preparing to migrate content from Navigator to Atlas, it helps to know how many
Navigator entities will be extracted. Use Navigator's search facets for additional
details.
To determine the number of Navigator entities extracted for the extraction and
transformation phases of the migration perform the following steps:
Log into Navigator.
In the Cluster Group facet in the left panel,
select the cluster you are migrating from.
The main panel displays the count of entities in that cluster. Use this value for
estimating the extraction and transformation phase durations.
Not all Navigator entities are imported into Atlas. To estimate the subset of
entities included in the import phase:
Log into Navigator.
In the Cluster Group facet in the left panel,
select the cluster you are migrating from.
In the Source Type facet in the left panel, select
"Hive", "Impala", and "Spark".
The main panel displays the count of entities from
these sources in this cluster.
Double the number from the search results to account for the physical
files that correspond to the tables and jobs. The HDFS entities referenced by the
Hive, Impala, and Spark entities are included in the migration.
The migration brings over all business metadata definitions and associations
with migrationed entities. To determine the number of Navigator-managed properties to
migrate perform the following steps:
Log into Navigator.
In the left Search panel, find the Tags
facet.
This facet lists all the tags defined in Navigator. Navigator tags are
imported into Atlas as labels.
Go to Administration > Managed
Properties.
The Navigator namespaces are imported as Atlas
business metadata collections. Each managed property is imported as a business
metadata attribute.
