Preface

I recently found a cheaper cloud server and decided to move all my existing services over.
I originally planned to use 1Panel’s snapshot feature for a one-click migration, but here’s what I discovered:

The blog space (MX Space) cannot be fully migrated via snapshots.

So I had to do it manually—and I’m documenting the entire process here for future reference.

1. DNS Record Migration

First, point your domain to the new server.

1. Log in to your domain’s DNS provider
2. Update the A record → point it to the new server IP
3. Set a low TTL (e.g., 600 seconds) for faster propagation

Example:

Record Type Host Value ------------- ---------- ------------- A @ New server IP A www New server IP

Wait for the changes to propagate (usually 1–30 minutes).

2. Migrating the MX Space Server

1. Archive Data from the Old Server

All core MX Space data resides in the mx-space directory.

Example directory structure: /root/mx-space

Run on the old server:
cd /root
tar -czvf mx-space.tar.gz mx-space

2. Upload to the New Server

scp mx-space.tar.gz root@new-server-ip:/root/
cd /root
tar -xzvf mx-space.tar.gz

3. Start Docker Services

cd /root/mx-space/core
docker compose pull
docker compose up -d
docker ps

4. Common Follow-up Checks

ufw allow 80
ufw allow 443
ufw allow 22

apt update
apt install docker-compose-plugin -y

3. Deploying the Shiroi Theme (GitHub Actions)

Go to: Settings → Secrets and variables → Actions

Update the following: HOST / USER / PASSWORD / PORT / KEY / GH_PAT

Then run: Actions → Run workflow

4. Post-Migration Verification

1. Open your blog’s domain
2. Check that it loads correctly
3. Verify the admin dashboard
4. Test posts, images, and comments

Migration Summary

1. Update DNS records
2. Migrate /root/mx-space
3. Bring up services with Docker
4. Update GitHub Actions
