3 _Description: Layout of RRD files has changed
4 The layout of the RRD files created by collectd has changed significantly
5 since version 3.x. In order to keep your old data you have to migrate it.
6 This can be done by using /usr/lib/collectd-core/utils/migrate-3-4.px.
7 .
8 This step requires both the perl and the rrdtool packages to be installed,
9 which is currently not the case. You need to perform the migration manually.

16 _Description: Automatically try to migrate your RRD files?
17 The layout of the RRD files created by collectd has changed significantly
18 since version 3.x. In order to keep your old data you have to migrate it.
19 This can be done by using /usr/lib/collectd-core/utils/migrate-3-4.px.
20 .
21 This step can be done automatically. In this case a backup of
22 /var/lib/collectd/ is made in /var/backups/. This script is still
23 experimental, though. Do not expect it to work in all cases.

30 _Description: Remove all collected data (e.g. RRD files)?
31 The /var/lib/collectd/ directory which contains the data files containing the
32 collected statistics is about to be removed. For example, this directory
33 includes (in the default configuration) all RRD files.
34 .
35 If you're purging the collectd package in order to replace it with a more
36 recent or custom version or if you want to keep the data for further
37 analysis, the data should be kept.
