Welcome to our Plesk Community

If you are still using CentOS 7.9, it's time to convert to Alma 8 with the free centos2alma tool by Plesk or Plesk Migrator. Please let us know your experiences or concerns in this thread:

Please beaware of a breaking change in the REST API on the next Plesk release (18.0.62).
Starting from Plesk Obsidian 18.0.62, requests to REST API containing the Content-Type header with a media-type directive other than “application/json” will result in the HTTP “415 Unsupported Media Type” client error response code. Read more here

Upgrade Steps?

Hello,

I am preparing to upgrade from Plesk 8.4 for Windows to version 9.0. I am also upgrading SiteBuilder. I am going from version 4.2 to 4.5. Should it be upgraded before or after upgrading Plesk? Does it matter?

What about other components? Before or after Plesk upgrade?

I am reading the following links: http://download1.parallels.com/Plesk...windows.html#6, http://download1.parallels.com/SiteBuilder/Windows/4.5/sitebuilder-4.5_build080902.182_win.html
Are there any other links I should also read in preparing for these upgrades?

Any advice, information or lessons learned on doing either or both upgrades will be welcomed!

BTW: I have also posted this at http://forum.swsoft.com/showthread.php?p=222791#post222791 since it involves both Plesk and SiteBuilder upgrades.

Thank you,
Dawn
