Migration to the new Active24 platform – technical changes

In order to improve the quality of our services, we as Active24 s.r.o. have co-operate with our sister company Websupport s.r.o. and have created a new platform to which we are gradually transferring all customer accounts.

Although we try to make the migration as seamless as possible for our clients, migrating to a different platform and therefore a different infrastructure can have a number of impacts that need to be taken into account.

In this article, we’ll cover the major changes that could affect your services, whether it’s your website, domains, or emails, especially if you use 3rd party applications or have a custom website.

The changes mentioned in this article will only take effect once your account has been migrated to the new platform. You will be notified by email when the migration is complete.

If you are unsure whether any of the following changes apply to you, contact your webmaster or the IT technician who manages your services to check the matter.

Changes to DNS records

If you have domain registered with us and use nameservers (DNS servers) from us, nothing changes for you and we will make any changes from our side.

If you are using another registrar, you may also receive information emails from the central domain registry about changes to your domain settings.

If you use different DNS (nameserver) provider, you will then need to modify the DNS records with your DNS administrator. We will inform you about this change.

Changes will need to be made to both the domain settings for hosting and for emails, you can find the specific settings in the relevant articles or in the administration.

Access to email on your device

If you use email clients (Outlook, Thunderbird, Mac Mail, have Gmail connected or use an application on your mobile phone) you will need to adjust the settings in this email client for the new email servers (IMAP/POP and SMTP) after migration.

For Outlook as the most widely used email client we have prepared a separate article.

For other email clients, you can find the settings for adding a mailbox in other articles or you can look up the instructions from the email client creator online.

You can find the new server values in the Webadmin administration by clicking on the details of your email or in our knowledge base article.

Email aliases

Email aliases will no longer be used for sending messages. The email alias will only be used for receiving mail. If you are actively using an email alias to send messages, you would need to cancel the alias and set up a separate mailbox.

Domain aliases for email

Domain aliases work the same for the hosting emails.

If you are using Active24 Email solution, domain aliases for email will no longer work – this service is discontinued.

Local delivery

The option to disable local delivery, i.e. that messages will not be stored in the mailbox, is not available on the new platform. If you have forwarding set up and do not wish to save messages to the mailbox, you can set a rule to delete messages directly in the email. Instructions for setting up the rules can be found in the respective instructions for email hosting or Business mail.

Postmaster mailbox

The postmaster mailbox was kept on the old platform as a system mailbox. Thanks to the new mail server setup, it is no longer needed on the new platform. In case you do not use the mailbox otherwise and would like to remove it, you can do so in your account administration in the Emails section.

FTP

For security and technical reasons, we do not transfer your previous FTP and SSH login details. Please set up a new one in the administration.

If you need help with the setup, you can use our guide.

Web FTP access can now be found at ftp.active24.cz.

Databases

Although the database login remains the same, the host (server) of the database changes. If you use the database only with our hosting within well-known content management systems such as WordPress or Joomla, everything is fine and nothing changes for you – we will make the configuration change from our side.

If you are connecting to the database from an external application or have a custom website, you will need to modify the database settings. You can find it in the new Webadmin administration. You can also get help with the settings in this article.

You can now find the database management via our online interface at dbadmin.active24.cz.

Root directory change

In case you originally had a site on our old platform, you may be surprised by the change in the root directory.

If you have set the path to a file in your web presentation absolutely (e.g. in the form /www/doc/www.domain.cz/www/file.php), we recommend setting it relatively via code:

$source = __DIR__ . ‘/’;

Sending from hosting via PHP mail()

We have increased security measures on the new hosting. Sending using the PHP mail() function is limited to mailboxes created with us. For more information you can read this article.

Python

Python scripts are no longer supported on the new platform.

Security plugins

During the migration, the server on which your website is running changes. Some security plugins (e.g. WordFence) may not tolerate the change of server (and therefore IP address) well. Please contact your webmaster, who will look into the settings of your security plugins in case of problems.

Server settings

On our new platform, the servers are now set up differently and therefore certain PHP settings and server settings may differ slightly. All servers have higher limits than on the original platform to ensure smooth running of the site, especially if you are using content management systems such as WordPress, Joomla etc.

If you use special settings on your website, we recommend that you check your website settings against our hosting parameters or phpinfo.
