Migrating a Windows File Server

Copy a Windows file server you administer, keep the source, and leave /MIR out of the first run.

Updated 25 October 2026 · How-To

This is an original planning guide. It is not a vendor manual, an official standard, or legal advice. Example addresses use documentation ranges. Review every command before you paste it.

What this hour is for

A migration copies, verifies, and only later cuts over. The script generator drafts the copy. It does not connect. The source server stays intact through this hour. Deleting the source is a different ticket after people have used the new path.

Both servers are ones you administer. /MIR can delete files on the destination. It is not the first run. Shares and NTFS permissions are the permissions page. Do not widen them to make the copy look easy.

Do not run the script during the reading. 192.0.2.10/24 and example.com are documentation. They stay in the note.

The change you can finish

Apply nothing while you are writing the note. When the lab window opens, it is one change on the host named in the ticket. Read the draft, then the host, then decide.

Rollback is the file, the package version, or the snapshot you saved first. You do not invent a rollback after the only copy is gone.

  1. Name the source and the destination.
  2. Confirm you administer both.
  3. Draft a copy without /MIR.
  4. Write how you will verify.
  5. Do not delete the source.
  6. Do not run it during the reading.

Mistakes that outlive the command

Migrating a Windows File Server goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.

Decisions to write down

One decision for Migrating a Windows File Server: Both servers are yours. The first draft does not mirror-delete. The source remains. Verification is a sentence. And nothing was run yet.

Checks before you call it done

Confirm this before you call the change done: Source and destination are written. /MIR is absent. The source is marked kept. Nothing was run. And the verify step is named. If one of those fails, stop.

# Keep the source.
# No /MIR on the first run.
# Both servers are yours.
# Do not run during the reading.

Before you leave the host

Migrating a Windows File Server ends when the hostname in the prompt matches the hostname in the ticket. If it does not, you are on the wrong host. Stop. A command that succeeded on the wrong host is not progress.

The draft stays a draft until a person has read the names in it. A generator does not log into the host and does not know which disk is empty. You delete a line that names a host, a path, or an account you did not write down.

192.0.2.10/24, gateway 192.0.2.1, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. They belong in the note. They are not values you leave on a host because a draft included them.

prompt-for-this is a reminder that a secret is missing. It is not a password, a key, or a token you save in the ticket or in git. The real secret stays in the password store.

One change is the window. If two things move and the result is wrong, you will not know which one did it. The next change waits for its own page.

If the same step fails twice, stop for the day. The failure is the result. Adding a forum command beside a half-applied change produces a host nobody can rebuild. Restore the copy you took first.

A second person reads the hostname and the change aloud. If they cannot find them in the ticket, the note is not done. Silence is not agreement. Then leave the host alone.

This page is a planning guide. It is not a vendor manual, not an official standard, and not permission to touch a host you do not administer. You do not disable a firewall, AppArmor, or SELinux to make a check pass.
