In Migration Center, a group is a set of assets, such as
servers and databases. You can include a server or a database in one or
more groups.
Groups let you organize your assets by functional characteristics or other
features. For example, you can group together all the servers and databases
that belong to the same application.
In the Group details page, enter the following information:
Name. The name of the group, for example the application
name. When you enter a name, an ID is automatically generated, which
you can choose to edit.
Description. Optionally, provide a short description of the group.
To confirm, click Next.
In the Add servers page, from the list of servers, select all the
servers that you want to add to the group, then click Next.
If you don't want to add servers, you can skip this step.
In the Add database deployments page, from the list of databases,
select all the databases that you want to add to the group.
If you don't want to add database deployments, you can skip this step.
To create the group, click Create.
Add and remove assets from a group
After you create a group of assets, you can add or remove assets.
From the list of groups, select the group to which you want to add assets.
On the group details page, follow these steps:
If you want to add servers, in the Servers tab,
click Add servers. Then, in the new page that opens, select all the
servers that you want to add to the group, then click Add.
If you want to add database, in the Database deployments tab,
click Add database deployments.
Then, in the new page that opens, select all the database
deployments that you want to add to the group, then click Add.
To remove assets from a group, follow these steps:
From the File format list, select Asset group data (CSV).
Click Select file to upload.
Select one CSV file of up to 100 MB to upload.
If your edited CSV file exceeds the 100 MB limit, you might need to split
it into smaller files and upload them in separate import jobs.
Click Upload files.
Keep the page open while the file upload is in
progress to make sure that the file upload does not fail.
Migration Center creates the import job and starts validating your
file. On the Data import page, check the job status for results and
any reported errors.

For example, you can group together all the servers and databases\nthat belong to the same application.\n\nCreate groups of assets\n-----------------------\n\nTo create a group of assets, follow these steps:\n\n1. Go to the **Groups** page.\n\n [Go to Groups](https://console.cloud.google.com/migration/discovery/groups)\n2. Click add **Create group**.\n\n3. In the **Group details** page, enter the following information:\n\n 1. **Name**. The name of the group, for example the application name.

For example, filter assets based on the OS or contributing source. To select more assets than those displayed on the page, select at least one asset, then click format_list_bulleted **Select all**.\n6. In the **Add database deployments** page, from the list of databases,\n select all the databases that you want to add to the group.\n If you don't want to add database deployments, you can skip this step.\n\n7.

[Import modified asset group assignments](/migration-center/docs/import-asset-group)\n\n### Export asset group assignments\n\nTo export asset group assignments, follow these steps:\n\n1. Go to the **Groups** page.\n\n [Go to Groups](https://console.cloud.google.com/migration/discovery/groups)\n2. Click **Import groups from file**.\n\n3. To get the template with your current asset group data, click **Export Template**.\n\n You can download this data as CSV files or export it to Google Sheets\n for editing.\n\n### Modify asset group assignments\n\nTo modify asset group assignments, follow these steps:\n\n1. Open the CSV file and edit the **Groups** column to modify or assign\n groups to assets.\n\n The group name must meet the following requirements:\n - Must be 3 to 63 characters long.\n - Must start with a lowercase letter (`a-z`).\n - Must end with a lowercase letter (`a-z`).\n - Must contain only lowercase letters (`a-z`), numbers (`0-9`), or dashes (`-`) between the first and last characters.\n2. Optional: To assign multiple groups to the same asset, use one of the following\n methods:\n\n - List the asset on multiple rows, using the same asset name on each row but a different group name for each row.\n - List multiple groups in one cell, keeping the assets on a single row. In the groups column, enter each group name on a separate line in the cell.\n3. Save and export the modified CSV file.\n\n### Import modified asset group assignments\n\nTo import the modified asset group assignments from a CSV file, follow these steps:\n\n1.

If the files are validated correctly, to import the modified group assignments,\n click **Import** data, then click **Confirm**.\n\nOut of scope assets\n-------------------\n\nMarking assets as out of scope hides them from the groups.\nWhen you put an out of scope asset back in scope, it keeps\nits original group memberships.\n\nWhat's next\n-----------\n\n- Learn how to [export data for your assets](/migration-center/docs/export-inventory-and-performance-data)."]]
