High Level Upgrade Process
5
--------------------------
7
In broad terms, there are 3 steps involved in upgrading to Bazaar 2.x:
9
1. Upgrade the core software
11
2. Upgrade required plugins
13
3. Migrate data to the new default format.
15
Bazaar 2.x supports branches in earlier formats so the third step is
16
strictly not required. However, the new default format in Bazaar 2.x
17
is more space efficient, faster on large projects and provides a range
18
of new features, so it is recommended that most projects migrate to it
21
For most users, upgrading to 2.x and migrating to the new format is
22
straight forward. For projects with a large community of developers
23
though, things become more complex. In these cases, careful planning
24
and good communications become essential. This document provides
25
general advice which aims to assist in this regard. If in doubt,
26

27
questions or concerns you have.

Upgrading the core software
31
---------------------------
33
The steps required to upgrade the core software vary from operating
34
system to operating system. There is nothing special about upgrading
35
from Bazaar 1.x to Bazaar 2.0 compared to upgrading from Bazaar 1.x
36
to Bazaar 1.y. In either case, a brief outline of the steps is given
39
To upgrade Bazaar on Linux:
41
1. Ensure your package manager is configured with the required
42
software sources, e.g. the official release PPA for Ubuntu:
43
https://launchpad.net/~bzr/+archive
45
2. Use your package manager to upgrade to the latest version.
47
To upgrade Bazaar on Windows:
49
1. Uninstall the existing version using Add/Remove Programs.
51
2. Install the new version using the relevant installer.
53
To upgrade Bazaar on OS X (via the installer):
55
1. Uninstall the existing version by deleting the relevant
58
2. Install the new version using the relevant installer.
60
To upgrade Bazaar on OS X (via MacPorts):
62
1. Refresh the package metadata using **sudo port selfupdate**
64
2. Upgrade to the latest version using **sudo port upgrade bzr**

70
Upgrading required plugins
71
--------------------------
73
Many plugins are not dependent on a particular Bazaar version so
74
upgrading them is optional. Other plugins, notably bzrtools and
75
bzr-svn, are more tightly associated with Bazaar's APIs so these
76
typically need to be upgraded in lockstep with the core software.
78
For Windows and OS X users, bzrtools and bzr-svn are typically
79
included in the installer so no special steps are required to upgrade
80
these. For Linux and UNIX users, bztrools, bzr-svn and many other
81
popular plugins can be installed and upgraded using your
82
platform's package manager, e.g. Synaptic on Ununtu.
85
Migrating data to the new default format
86
----------------------------------------
88
As mentioned earlier, the complexity of migrating to a new format
89
depends on several factors, particularly project community size.
90
It also depends on how data is currently stored, e.g. in a
91
standalone branch, multiple branches in a shared repository,
92
stacked branches on Launchpad, etc. These various scenarios are
93
covered in the next chapter.
