许可证指南

如何激活 Plus 或 Pro

购买之后 you receive a license key (MMIG-…). Install Multisite Migrate Pro, enter the key under Settings → General & License, and click Activate. Takes a few minutes.

购买之后

Plus / Pro.

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

下载 Pro

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

Sign in at 我的账户.
Download the Multisite Migrate Pro ZIP for your plan.
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.

安装插件

Plus / Pro.

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

激活许可证密钥

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

Go to Multisite Migrate → Settings → General & License.
Paste your key (MMIG-…) into the license field.
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.

激活次数与席位

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: 了解站点限额.

故障排除

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 我的账户.
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.
