Download als PDF FileCisco Prime Infrastruktur ist ein tolles Tool. In der Version 2.0 werden nun endlich auch die neuen WLAN Controller (5670, 3850, 3650) mit dem Converged Access Ansatz unterstützt. Vor dem Upgrade sollte man nicht zuviel Angst haben, dennoch sollte man die Release Note sorgfältig durchlesen.
Nebst den „Supported Devices“ sind wohl die Upgrade Requirements die wichtigsten Punkte die man beachten muss
You can upgrade the following NCS/Prime Infrastructure 1.x versions to Prime Infrastructure 2.0:
- 1.1.1.24 with patch ncs_1_1_1_24-Update.13.4.tar.gz
- 1.2.1.12 with patch PI_1_2_1_12-Update.1.0.tar.gz
- 1.3.0.20 with patch PI_1_3_0_20-Update.1.12.tar.gz and/or PI_1_3_0_20_Update.4-16.tar.gz
- 1.2.1.12 (migrated from 1.2.0.103) with patch PI_1_2_1_12u-Update.1.tar.gz
The following NCS/Prime Infrastructure 1.x backups can be restored to Prime Infrastructure 2.0:
- 1.1.1.24 with Patch ncs_1_1_1_24-Update.13.4.tar.gz
- 1.2.1.12 with Patch PI_1_2_1_12-Update.1.0.tar.gz
- 1.3.0.20 with patch PI_1_3_0_20-Update.1.12.tar.gz and/or PI_1_3_0_20_Update.4-16.tar.gz

The following NCS/Prime Infrastructure 1.x versions cannot be upgraded or restored to Prime Infrastructure 2.0:

Wie vor jedem Update empfiehlt sich ein komplettes Backup der Datenbank. Dabei ist zu beachten, dass man von der Prime CLI zwei Arten von Backups erstellen kann.
#backupfilenamerepositoryrepositoryName
Backuped die gesamte Cisco Prime Installation, inkl. OS. Ein Restore kommt somit einem Snapshot restore gleich.
# backup filename repository
repositoryNameapplication NCS
Backuped nur die Konfiguration, ein Restore kann auch in eine hoehere Version wie bswp. 2.0 importiert werden. Ich empfehle diesen Schritt zu machen, so behält man sich bei einem missglückten Upgrade die Option offen eine Neuinstallation mit Restore zu machen.
Sollte Prime virtuell als VM laufen, ist ein Snapshot auf jeden Fall pflicht. Allerdings gewinnt man nicht wirklich, wenn man den Snapshot zurückspielt.

Nachdem das Upgrade durchlief, war das Webinterface von Prime leider nicht mehr ansprechbar, auf der CLI sah man den Grund:

Vorsicht, Goggled man etwas wird man auf einen Bug verwiesen und entsprechend ein Update auf Prime 2.0.3 empfohlen. Allerdings genügte in meinem Fall ein Stop/Start des NCS
