This chapter is intended for hosting service customers who previously used Plesk version 9 and earlier. It describes the most important changes in Plesk and addresses possible issues that the users might encounter after their accounts and sites are moved to Plesk 12.5 during the Plesk upgrade.
The concept of a domain has been replaced with a concept of a subscription - a hosting unit able to run multiple sites (domains and subdomains) over given resources and services. Multi-domain hosting within one subscription is limited to one IP address. Customers who need to host sites on different IP addresses are advised to obtain additional subscriptions.
Customers no longer need to redistribute their resources across domains or subscription: Each subscription is allocated a fixed set of resources according to a hosting plan.
All sites in a subscription typically share the same SSL certificate. It is also possible to have per-domain certificates in case Plesk supports SNI.
To protect all subdomains in a subscription with one certificate, customers should consider purchasing a multi-domain (a wildcard) SSL certificate.
Presence Builder is a Plesk component that allows fast and efficient creation of websites. When Plesk with SiteBuilder is upgraded to Plesk 12.5, the SiteBuilder component is not actually upgraded. Instead, the new Presence Builder is installed on the server, and SiteBuilder 4.5 remains operable; however, operations on websites created in SiteBuilder 4.5 are limited to editing and publishing.
Presence Builder allows websites created in SiteBuilder 4.5 to be imported. However, this feature has certain limitations: some elements may be missing or corrupted in the imported website. We advise you to compare it with the original version and add the missing content manually.
See the section Importing Sites from SiteBuilder 4.5 for more details on importing SiteBuilder 4.5 sites to Presence Builder.
The option to use a separate directory for storing web content that should be accessed over secure SSL connections is no longer available. All web content is now stored in a single directory - httpdocs
.
The httpsdocs
directory may remain in the webspace after upgrading to Plesk 12.5, however, we recommend that you place all content in the httpdocs
directory when uploading files to the webspace over FTP.
If you used the option to keep SSL-protected and all other content in separate directories, and had APS-packaged applications installed in the httpsdocs
directory of a website, then after upgrade, Plesk will switch on the compatibility mode for that site. This will make the apps previously installed into httpsdocs
directory accessible to the Internet users, but the apps will not be manageable through Plesk, and you will not be able to install new apps to the httpsdocs
directory.
In such a case, if you have the necessary technical skills, you can do the following:
httpsdocs
directory and save it to another location. Do not move the files to httpdocs
yet.httpsdocs
directory. You can do this with the help of the mysqldump
utility.httpsdocs
directory.httpdocs
directory.If you are an inexperienced user, we recommend that you leave the previously installed applications and uploaded content in the httpsdocs
directory, and host new applications on other websites. If you need to install apps on the site operating in compatibility mode, you can install them to the httpdocs
(http://) location on that site.
