How to activate Plus or Pro

After purchase

Plus / Pro.

1. Check your inbox for the Multisite Migrate welcome email — it includes your license key and a sign-in link.
2. You can also open your key anytime in My Account after signing in with the magic link from that email.
3. Keys look like MMIG-…. Keep them private; treat them like passwords.

Download Pro

Plus / Pro. Licensed builds ship as a ZIP from your account (not from WordPress.org alone).

1. Sign in at My Account.
2. Download the Multisite Migrate Pro ZIP for your plan.
3. If you already run Free from WordPress.org, you can keep Free for local backups — or replace it with the Pro ZIP so Plus/Pro features unlock after activation.

Install the plugin

Plus / Pro.

1. In WordPress: Plugins → Add New → Upload Plugin → choose the ZIP → Install Now → Activate.
2. On Multisite: use Network Activate so network admins can run network-wide jobs.
3. Open MM Pro in the admin sidebar — you land on Backups.

Activate your license key

Plus / Pro. No wp-config.php changes required.

1. Go to Multisite Migrate → Settings → General & License.
2. Paste your key (MMIG-…) into the license field.
3. Click Activate. The page should show an active license and remaining install activations.

After a successful activation, Plus/Pro menus (Cloud, Schedules, Staging, WP-CLI where applicable) become available according to your plan.

Activations vs seats

Plus and Pro use two related limits. Same numbers (3 or 10) — different things.

• License activations — how many separate WordPress installs (single site or one multisite network) may use this key. Shown under Settings → General & License.
• Subsite admin seats — Multisite only. How many subsites you enable for subsite administrators. Shown under Settings → Site access.

Full explanation: Understanding site limits.

Troubleshooting

• Invalid key — Confirm you pasted the full MMIG-… string with no extra spaces. Keys are case-sensitive.
• Activation limit reached — Deactivate the key on an unused install under Settings → General & License, or upgrade / add capacity from My Account.
• Cannot reach license server — Your host must allow outbound HTTPS to the Multisite Migrate license API. Check firewall / security plugins if activation hangs or fails.
• Still on Free UI — Confirm you installed the Pro ZIP (not only the wp.org Free plugin) and that activation succeeded.
