• Be assumption that you have fully permission and activate Network Admin. By the way, prepare WordPress theme as format `.zip` file.

• Access Network Admin of your WordPress website by using WP Engine account. Navigate to Appearance » Theme:

Note: Let set up Engitect in Network Enable status.

• The next step, we will establish theme for sub website by navigating to Sites » All Sites and open tab Themes.

Note: Using All-in-One WP Migration to migrate other WordPress site to sub site in WP Engine. That is one of suggestion to minimize our effort.

Let enable it! and move to sub site `Flagtick Blog`. You can see the theme and can activate it.

That's all.
