Upgrading on Debian / Ubuntu¶

Core system¶

Running 6.3 or higher¶

To upgrade minor releases run:

apt-get update
apt-get install groupoffice

Major release upgrade¶

When the second digit increases in the version number we call this a major release. For example when upgrading to 6.4 from 6.3. When upgrading to the next major release follow these steps prior to the above:

Run the above command first to upgrade to the latest 6.3.
Then open your browser to update the database.
Then you need to adjust the repository in:
```
/etc/apt/sources.list.d/groupoffice.list
```
For 6.4 change it to:
```
deb http://repo.group-office.com/ 64-php-71 main
```
Or when running PHP 7.0 :

deb http://repo.group-office.com/ 64-php-70 main

From older versions than 6.3¶

First checkout the blog post about this release
6.3 offers quite a lot of changes. It’s strongly recommended to upgrade in a test environment first.
After the upgrade you should consider replacing the “gota” module with the new “assistant” module for better file editing on the desktop.
Typically the Custom CSS module was used to replace the logo. To take advanage of the new System Settings -> Appearance features you should remove this CSS code.
If you customized language then you should convert this to the new language Customize system.
If your system is older than 6.2 your system probably depends on mcrypt. If you migrate to a new server and you run into email password problems you might need to install https://pecl.php.net/package/mcrypt to decrypt email passwords. If you have plaibn MD5 hashes in your pa_mailboxes database table run this SQL query:
```
update `pa_mailboxes` set `password` = concat("{PLAIN-MD5}", `password`);
```

Make sure you’re on the latest 6.2 version.
Make sure you’ve installed the “customfields” and “search” modules as they will become part of the Group-Office core.
Uninstall the old “groupoffice-com” package but do NOT deconfigure the database:
```
apt-get remove groupoffice-com
```
If you made manual changes inside /usr/share/groupoffice (Like installing z-push for example). The the package manager will leave these folders intact. To avoid problems move /usr/share/groupoffice away before installing:
```
mv /usr/share/groupoffice /root/groupofficebak
```

Edit /etc/apt/sources.list and remove:

deb http://repos.groupoffice.eu/ sixtwo main

Now do a fresh install of the 6.3 Debian package. But note:
- When the installer asks to install a database choose “NO”.
- When the installer asks to replace /etc/groupoffice/config.php, choose “Keep the local version currently installed”.
- Use 63-php-70 or 63-php-71 for the repositiory instead of the 6.4 one.

Continue at Installation on Debian or Ubuntu.

Mailserver¶

If you’re upgrading from a previous 6.3.x or higher version simply run:

apt-get install groupoffice-mailserver

Or if you also installed the anti spam and virus package:

apt-get install groupoffice-mailserver groupoffice-mailserver-antispam

Upgrading from 6.2¶

1. To upgrade from 6.2 you must start with a clean system by removing all previous software and configuration. Make a backup!:

apt-get purge groupoffice-mailserver dovecot* postfix* clamav* spamassassin amavisd-new

Then install the new package:
```
apt-get install groupoffice-mailserver
```

Move the mail to the new location:

mv /home/vmail/* /var/mail/vhosts
rmdir /home/vmail

Remove no longer required packages:
```
apt-get autoremove
```
