Procedure

Stop your instance of the previous version of Talend Data Stewardship but keep MongoDB running.

Back up your MongoDB by running the following command.

For Linux:

<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>

For Windows:

<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>

For more information, see the MongoDB documentation.

After backing up the MongoDB, stop the instance.

Install and start MongoDB 4.x.
Talend Data Stewardship 8.0 supports MongoDB version 4.x and 3.6.
Delete the database:
1. Open a mongo shell as a Talend Data Stewardship database user and execute the following commands.
  For Linux:
```
cd <install_dir>/mongodb/bin
./mongo tds -u tds-user -p duser --port 27017
```
  For Windows:
```
<install_dir>\mongodb\bin>mongo tds -u tds-user -p duser --port 27017
```
2. Switch to the Talend Data Stewardship database: use tds
3. Drop the database: db.runCommand( { dropDatabase: 1 } )
4. Exit mongo shell: exit
Restore the MongoDB backup by running the following command.
For Linux;
```
<mongo_path>/bin
./mongorestore -h <mongo_host>:<mongo_port> -u <mongo_tds_username> -p <mongo_tds_password> -d <mongo_tds_database> <backup_location>
```
For Windows:
```
<mongo_path>/bin>mongorestore -h <mongo_host>:<mongo_port> -u <mongo_tds_username> -p <mongo_tds_password> -d <mongo_tds_database> <backup_location>
```
For the previous version of Talend Data Stewardship, if you have customized the <Data_Stewardship_Path>/conf/data-stewardship.properties file, you can copy the values from the old configuration file to the new file.
Install Talend Data Stewardship 8.0 and select the external MongoDB option. Make sure to configure it with the same settings as the previous instance and link it to your Talend Administration Center.
If you have installed Talend Data Stewardship 8.0 in service mode, stop the instance of MongoDB.
Delete the <install_dir>/tds/apache-tomcat/data folder from your Talend Data Stewardship 8.0 installation.
Start Talend Data Stewardship 8.0.
