# Verify files before and after a server upgrade

Both before and after you upgrade the server, we recommend that you use the p4 verify command:

1. Before the upgrade, verify the integrity of:

   1. submitted file revisions by running:

      $ p4 verify -q //...

   2. shelved files (if any) by running:

      $ p4 verify -qS //...

2. Take a checkpoint.
3. Copy the checkpoint and your versioned files to a safe place.
4. Perform the server upgrade.

5. After the upgrade, verify the integrity of

   1. submitted file revisions by running:

      $ p4 verify -q //...

   2. shelved files (if any) by running:

      $ p4 verify -qS //...
