Question

How to check a Plesk server for possible issues before the upgrade?

Answer

It can be done using the pre-upgrade checker script.
Follow the instructions below to use it.

Plesk Obsidian 18.0.32 and newer

  1. Connect to the server using SSH or RDP.

  2. Use the pre-upgrade checker:

    • To list available upgrades:

      # plesk listupgrade

    • To run the pre-upgrade checker for checking the upgrade to the latest available version:

      # plesk checkupgrade

    • To run the pre-upgrade checker for checking the upgrade to specific version:

      # plesk checkupgrade 18.0.33

Plesk Obsidian before 18.0.32, Plesk Onyx 17.x, Plesk 12.x

  1. Connect to the server using SSH or RDP.

  2. Download the archive with the pre-upgrade checker and unpack it:

    • on Linux:

      # wget https://support.plesk.com/hc/en-us/article_attachments/12377929412759/preupgrade_checker_linux.tar.gz
      # tar -xzvf preupgrade_checker_linux.tar.gz

    • on Windows: use the URL https://support.plesk.com/hc/en-us/article_attachments/12377929344151/preupgrade_checker_windows.zip and unpack the archive using a preferred tool.

  3. Use the pre-upgrade checker:

    Note: On 32-bit operating systems, use the binary preupgrade.386 instead of preupgrade.x64.

    • on Linux:

      • To list available upgrades:

        # ./preupgrade.x64 list

      • To run the pre-upgrade checker for checking the upgrade to the latest available version:

        # ./preupgrade.x64

      • To run the pre-upgrade checker for checking the upgrade to specific version:

        # ./preupgrade.x64 18.0.33

    • on Windows:

      Note: On 32-bit operating systems, use the binary preupgrade_x32.exe instead of preupgrade_x64.exe.

      • To list available upgrades:

        .preupgrade_x64.exe list

      • To run the pre-upgrade checker for checking the upgrade to the latest available version:

        .preupgrade_x64.exe
