Before you begin
If you have installed and used Talend Dictionary Service to
create custom semantic types or update the predefined ones, you must migrate Talend Dictionary Service
before migrating Talend Data Stewardship. See
Migrating Talend Dictionary Service to version 8.0.x R2022-07 or later.
Download the hybrid Talend Data Stewardship 8.0
archive from Talend Cloud's
Downloads page.
Procedure
-
Stop your current Talend Data Stewardship instance but keep MongoDB running.
-
Back up the MongoDB instance used for the previous version of
Talend Data Stewardship using the
following command:
<mongo_path>/bin/mongodump -h <source_mongodb_host>:<source_mongo_port> -u <mongo_tds_username> -p <mongo_tds_password> -d <mongo_tds_database> -o <backup_location>
The default value for the embedded MongoDB properties are the
following:
Property |
Value |
mongodb.host
|
localhost
|
mongodb.port
|
27017
|
mongodb.database
|
tds
|
mongodb.user
|
tds-user
|
mongodb.password
|
duser
|
-
Stop the MongoDB instance from the previous version of Talend Data Stewardship.
Note: For Windows users, you
must uninstall the current MongoDB before you install Talend Data Stewardship
8.0.
-
Install Talend Data Stewardship 8.0
and select the embedded MongoDB option. Do not start the instance.
If you have installed Talend Data Stewardship 8.0
in service mode, stop the MongoDB instance.
-
Delete the database
-
Open a mongo shell as a Talend Data Stewardship database user and
execute the following commands:
cd <install_dir>/mongodb/bin
./mongo tds -u tds-user -p duser --port 27017
-
Switch to the Talend Data Stewardship database:
use
tds
-
Drop the database:
db.runCommand( { dropDatabase: 1 } )
-
Exit mongo shell:
exit
-
Restore the MongoDB backup on the new 8.0 MongoDB instance by using the following
command:
<mongo_path>/bin/mongorestore -h <mongo_host>:<mongo_port> -u <mongo_tds_username> -p <mongo_tds_password> -d <mongo_tds_database> <backup_location>
-
If you have customized the <Data_Stewardship_Path>/conf/data-stewardship.properties
file in the previous version, you can copy the values from the old configuration
file and add them to the new version. You can then change
parameters needed for Talend Cloud and
Talend Management Console, as explained in Configuring Talend Data Stewardship after installation.
-
Delete the <install_dir>/tds/apache-tomcat/data folder
from your Talend Data Stewardship 8.0
installation.
-
Start Talend Data Stewardship
8.0.
-
Republish semantic types using Talend Dictionary Service API to migrate indexes to Lucene 8.
