New page

This page describes what you have to do to change the name of an RT instance (rtname [[SiteConfig]] option).

== Pristine Instance ==

If you've just installed RT and have not created any tickets as of yet, you only have to

* change the instance name in the rtname [[SiteConfig]] option.

== Operational Instance ==

If there are already tickets in the instance, things are a little more complicated.

=== RT 3.6.x ===

In RT 3.6 a new EmailSubjectTagRegex config option had been added which makes renaming much easier. You have to do:

* change the name in the rtname config option.
* write regexp that matches both names: old and new one, and set EmailSubjectTagRegex option

For example old name is <code>old.name</code> and new one is <code>new.name</code>, then your config should look like:

Set($rtname, 'new.name');
Set($EmailSubjectTagRegex, qr/(?:old\.name|new\.name)/i);

This regular expression is required for some period of time only. Later you can delete this option when all active tickets will be using new subject line.

=== Older versions ===

* change the name in the rtname config option.
* set up an email filter that rewrite subjects or hack the [[EmailParser]] a little to understand the old value, so people don't get errors if they send messages with the old rtname in the subject.

In Postgres :

update transactions set data = replace ( data, '<OLDNAME>', '<NEWNAME>') where data ~ '<OLDNAME>';

update attachments set subject = replace ( subject, '<OLDNAME>', '<NEWNAME>') where subject ~ '<OLDNAME>';

and so on.
