After the upgrade is finished, these parameters should be set to their previously used values.
If you have Plesk version earlier than 8.1.x installed, then you need to upgrade it to Plesk 7.6.1 first, migrating all data, upgrade it to Plesk 8.1, and then run the Parallels Plesk Panel 9.5.4 installer. Refer to Plesk 8.1 Release Notes for additional information if you want to upgrade your Sitebuilder shipped with Plesk 7.6.1.
If your machine has Plesk 8.1.x, 8.2.x, 8.3.x, 8.4.x or 8.6.x installed, you will be prompted to upgrade the existing Plesk installation to Parallels Plesk Panel 9.5.4 after running the installer.
Parallels Plesk Panel 9.5.4 for Windows includes Sitebuilder 4.5 in the distribution package, but your Sitebuilder 2.x or 3.x installation will not be upgraded automatically. If you want to upgrade your Sitebuilder version during installation of Parallels Plesk Panel, run the installer executable with the following option:
If you used Sitebuilder 2.0.5 with earlier versions of Plesk, you can migrate websites created in Sitebuilder 2.0.5 to Sitebuilder 4.5 after you upgrade your Plesk software to Parallels Plesk Panel 9.5.4.

After you upgrade to Parallels Plesk Panel 9.x, all custom (third-party) skins will become unregistered to avoid visual issues.
Language packs for Plesk 8.x are not compatible with Parallels Plesk Panel 9.0.0 and later.

If an external Sitebuilder system (that is, Sitebuilder installed in SVE or VPS environment or on a remote server) is integrated with your Parallels Plesk Panel server, your customers will not be able to access Sitebuilder through Parallels Plesk Panel if they use Internet Explorer with default security settings. To resolve this issue, make sure that both Parallels Plesk Panel and Sitebuilder are located in one subnet (for example, 22.214.171.124 and 126.96.36.199).

If VZ MSDE template was installed after remote database servers were set up in Parallels Plesk Panel, working with remote database servers will be forbidden because VZ MSDE template switches the work mode from remote to local. To resolve this issue, you have to manually switch the work mode from local to remote.
