Transfer a trac database from one desktop to another

I'm using Trac 0.12.2 that came as a part of Bitnami Trac Stac.

I am very new to Trac & just开发者_开发问答 started with Trac, working with a local repository on a desktop a few weeks ago & created some issues. Now I wanted to transfer the all those issues onto my new Trac installation on another desktop. So I simply tried replacing the empty(I believed) database folder of new installation with my old Trac DB folder.

Specifically this folder:

C:\BitNamiTracStack\repository\db\

When I tried doing so, the admin tab on the trac interface disappeared.

Also I got a message:

   Warning: Can't synchronize with repository "(default)" (The repository directory has changed, you should resynchronize the repository with: trac-admin $ENV repository resync '(default)'). Look in the Trac log for more information. 

How do I successfully transfer my issues from one desktop to another ?

Check your installation and find the correct directory called 'Trac environment' as per Remy's advice.

While his answer is the safe road and general advice without doubt, you may still succeed with a less complete transfer, depending on what you already put into the Trac environment in question. Assuming you do use BitNami's default Trac db backend (SQLite) you'll need at least

• the latest db named trac.db from the db folder
• the configuration file conf/trac.ini

If you've worked with attachments to tickets or wiki pages, the whole directory structure below attachements is needed as well.

Other things might not have been touched by a self-declared "very new" Trac user within the first weeks. Of course a diff -Nur <path_to_old_dir> <path_to_new_dir> | <your_favorite_editor> will remind you of anything you may have already forgotten.

You shouldn't copy the database alone, but the complete Trac environment. That's the directory containing the attachments, conf, db, htdocs, log, plugins and templates directories. In your case, this seems to be the directory:

C:\BitNameTracStack\repository

(I'm not familiar with the BitNami stack, but the name "repository" sounds suspect. I hope they don't put the Trac environment below the Subversion repository.)

See the official Trac documentation on backing up a Trac environment and restoring it. You should be able to use this to migrate your config to another server.
