The first step in migration is plant migration. This enables plants to be migrated step by step to version v3.

After migration, the plant is no longer visible in v1.8.x.

To be able to perform the migration, log into the system as an administrator.

Note
	Performing a database backup before starting the migration is recommended.

Carry out the following steps to start the plant migration process:

1. Select the plant to be migrated and open the configuration view.

2. Go to the Migration tab.

3. Go through the checklist and follow the instructions.

4. Once you have followed the instructions, click on the <Apply> button for each.

5. Make sure that you have access to an up to date database backup and then check the An up to date database backup has been created and archived checkbox.

6. The <Start migration> button is then enabled and the plant is set to migration mode.

To start the migration, switch to the system settings under Migration > 1. Plant data migration and start the migration by clicking on the <Start migration> button.

The progress of the migration can be seen in the plant configuration under Migration.

Once all plants have been migrated, you can continue with the log migration, see chapter Log migration.
