What this usually means

Moving to a new computer is not only copying a Documents folder. Email, browser favourites, photographs, application data, licences, printers, cloud storage and account-recovery methods may all matter. The safest move starts by deciding what must arrive and making a separate backup before either computer is changed.

Prepare before the new computer arrives

  • List the files, email accounts, applications, printers and accessories you actually use.
  • Confirm important files exist in a separate backup that can be opened, not only on the old computer.
  • Check whether files are stored locally, in OneDrive or another cloud service, or in both places.
  • Make sure you can sign in to your own accounts and reach their approved recovery email or telephone number.
  • Record application names and legitimate licence information where required, without putting passwords in the list.
  • Check the new computer has enough storage, the right connections and support for essential applications or accessories.
  • Install all trusted operating-system updates before copying large amounts of data.
  • Keep the old and new computers together long enough to compare them properly.

Use a small, non-sensitive test folder first. Open several transferred files on the new computer rather than assuming a completed progress bar means everything is usable.

What to verify on the new computer

Check email sends and receives, cloud files have finished synchronising, common documents open, the printer works, browser favourites are present and essential applications are correctly licensed. Confirm desktop, documents and photographs rather than checking only one folder. If multiple people used the old computer, verify each person's data separately and keep access private.

What not to do

Do not wipe, trade in or recycle the old computer immediately. Do not copy unknown programs from download sites or move a potentially infected installation wholesale. Avoid sending passwords or recovery codes to someone helping with the move. A cloud synchronisation symbol is not proof that every required file is safely backed up.

When to stop and ask for help

Pause if the old drive clicks, important files are missing, account recovery is unavailable, encryption prompts appear or you are unsure which copy is current. If the old computer may be compromised, seek advice before signing into sensitive accounts on it. A careful assessment is safer than repeatedly attempting a failed transfer.

Prepare for support

Write down both computer models, the approximate amount of data, essential applications, email provider, cloud services, printer model and the date the old computer must remain available until. Explain what is already backed up and whether either device has faults. Keep passwords private; you should enter them yourself when needed.
