Before you start upgrading to newer activeCollab version please backup your old installation. Backup should include data from database and all files from the disk. If anything goes wrong with upgrade you should be able to easily restore old installation by simply copying old files and importing old data into database.
activeCollab 0.7 to activeCollab 0.7.1

First to point out, upgrade can work only from 0.7 to 0.7.1. If you are using older version than 0.7 you'll need to upgrade to 0.7 before you can upgrade to 0.7.1.

To upgrade activeCollab 0.7 to activeCollab 0.7.1 follow this instructions:

1. Create a backup of existing system, including installation files and content from your database. Please, don’t skip this step. If something goes wrong you’ll most probably end up with useless installation and you’ll be unable to go back.
2. Clean up old files – you should delete everything from the file system except contents form /config, /cache, /upload and /public/files folders.
3. Upload new files – simply upload new activeCollab files, but make sure that you don’t overwrite old files from /config, /cache, /upload and /public/files folder.
4. Execute upgrade script – Go to /public/upgrade/ page (for example: http://www.myactivecollab.com/public/upgrade/), select upgrade script (Upgrade 0.7 -> 0.7.1) and click on Upgrade button.
5. Let the script do the work – If something goes wrong you’ll receive an error message (red text). In that case you should restore your old installation (from backup) and submit a bug report in the Bug reports forum.

activeCollab 0.6 to activeCollab 0.7

1. Create a backup of existing system, including installation files and content from your database. Please, don’t skip this step. If something goes wrong you’ll most probably end up with useless installation and you’ll be unable to go back.
2. Clean up old files – you should delete everything from the file system except contents form /config and /public/files folders. They should remain intact because upgrade script will use data from that folders to upgrade existing database and keep your old files in place. It is important to delete files from old installation because new version will not work if it finds old files – it will break.
3. Upload new files – simply upload new activeCollab files, but make sure that you don’t overwrite old files from /config and /public/files folder.
4. Execute upgrade script – Go to /public/upgrade/ page (for example: http://www.myactivecollab.com/public/upgrade/), select upgrade script (Upgrade 0.6 -> 0.7) and click on Upgrade button.
5. Let the script do the work – it can take some time to transform old database and transfer all the data. If everything goes well you should see a bunch of green messages ending with a message telling you that upgrade process is done successfully. If something goes wrong you’ll receive an error message (red text). In that case you should restore your old installation (from backup) and submit a bug report in the Bug reports forum.
6. You’ll fail to login with your old login data. 0.7 version has a new login system and there is no way for it to read your old password value so you’ll need to reset it using Forgot password form. Just enter your email and hit submit button. You can notify all users by using mass mailer tool (in administration) or reset their password manually.
7. Check the bottom of the page if Forgot password form fails.

activeCollab 0.7 beta to activeCollab 0.7

1. Create a backup of existing system.
2. Drop all files except contents of /config, /public/files and /upload folders.
3. Upload files from 0.7 package but make sure that you don’t overwrite files from three folders listed in previous step.
4. That should be it. Just start using new version.

If Forgot password fails

You will need to manually update data into database. Open users table and find your administrator user (by username). Update that row and set:

token: 0a92df346e3a833cae214d65af35e69b3cf4e5ab
salt: 6d093346fa02f
twister: 4982716305

That will set password to '123'. Login and update you password. Make sure that mailing is working (you can use Test mailing configuration tool in administration).
