Prevent package reinstall when migrating from Avalanche 4.8 to Avalanche 6.1

When devices are migrated from Avalanche 4.8 to 6.1 it is likely that some or all of the packages will reinstall. This is not an ideal scenario if you have 1000s of devices reinstall apps.

To overcome this issue, one way is to Orphan the packages with no packages available for them to download in Avalanche 6.1. To do this lets look at the following example:

Scenario – Migrate Motorola MC3100 devices which have Telnet installed, from Avalanche 4.8 to Avalanche 6.1 without reinstalling Telnet or any other apps. If the device is rebuilt then the required apps should install.

Solution –

1.       Create 2 folders for the devices – one for the migrated devices and one for devices to be rebuilt in future

Migrated Devices folder will have the following selection criteria.

ModelName = MOTOMC3100 AND package.TN403000="OK"

This just means that if the device has Telnet installed then the device gets assigned to this folder. This folder will have no Profiles and hence no packages assigned. When devices with Telnet installed are migrated to Avalanche 6.1 they will fall in this selection criteria and not install/reinstall any packages. All the existing packages on the device will show “Orphaned”.

                                                                            

Rebuild Devices folder will have the following selection criteria:

ModelName = MOTOMC3100 AND (!(package.TN403000="OK" ))

This means that for a MC3100 device which does not have Telnet installed it will get assigned to this folder. This folder will have the necessary profiles and packages assigned for the device type. When a device is rebuilt it will not have Telnet installed and will fall in this folder and install the rest of its packages.

It is not necessary to use Telnet, I have just used it as an example, you can use any other package by replacing TN403000 in the selection criteria.
