Pre-Upgrade checklist

Before you upgrade, we encourage you to do a pre-upgrade checklist.

Table 1. Pre-upgrade checklist

Check

Tasks

References

 

Prepare and plan for downtime

  • Core (1 - 3 hours)
  • Sentry (5 - 20 minutes)

 

Review relevant documentation

Core product documentation page

 

Check certificates

  • iOS Enrollment, Portal HTTPS, Client TLS certificates

    NOTE: When using mutual authentication, the Portal HTTPS certificate must be a publicly trusted certificate from a well-known Certificate Authority. For details, see “Mutual authentication between devices and MobileIron Core” in the MobileIron Core Device Management Guide.
  • MDM Certificate (check a month before expires)
  • Local CA

Knowledge Base article: Renewing an expired local CA certificate.

 

Check Boot partition

Verify you have at least 35 MB free for /boot. See Check disk space availability in this document for details on how to perform this check.

Knowledge Base article: Core Upgrade: Increase Boot Partition to 1GM if Avail Space is less than 35MB.

 

Ensure there is enough disk space

  • Old File System (2 GB /mi and 5 GB /mi/files)
  • New File System (10 GB /mi)

Knowledge Base article: Resizing Disk Partition of a Core Virtual Machine.

 

Check for new system requirements

  • Minimum 80 GB hard drive
  • If there is insufficient storage, increase the available disk space using the procedure outlined in Resizing Disk Partition of a Core Virtual Machine
  • Call MobileIron support if issues persist when physical appliances and VMs have the minimum required disk space configured
  • Port 8443 for Summary MICS - MobileIron Configuration Service (that is, the service that supports System Manager.)

 

Review your backup and high availability options

  • Physical backup: built in backup, showtech all
  • VMware backup: VDMK backup, snapshot
  • High Availability: confirm HA version 2.0

Knowledge Base article: How to tell if your Core has HA 2.0
If using HA 1.0, contact MobileIron Professional Services to upgrade to 2.0.

 

Set up your proxy configuration (if required)

Manually set the upgrade URL and use HTTP instead of HTTPS.

 

Prepare test devices

  • Client: Get clean test devices, open client and check-in, check iOS log
  • Core: Note the watchlist and label numbers

Upgrade considerations

After the pre-upgrade planning, we recommend you review the following considerations:

DB Schema and Data

Run pre-validation check after downloading the repository from System Manager. If this task fails, contact MobileIron Support.

 

Understand the stages

  • Download vs. Stage for install
  • Reboot when the system displays:
    Reboot to install https://<serverFQDN>:8443/upgrade/status

 

Leverage CLI upgrade commands (as appropriate)

MobileIron Core Command Line Interface (CLI) Reference

 

Understand scenario options

  • Single server
  • High availability:
    Option 1: little downtime: 1) upgrade secondary 2) upgrade primary
    Option 2: zero downtime: 1) upgrade secondary 2) failover to secondary 3) upgrade primary 4) re-establish sync

Review section: HA Core Software Upgrade Procedures

 

Monitor the upgrade

  • Log into the Admin Portal
  • Select Logs > MDM Logs > States > Waiting xml generation pending
  • Monitor upgrade status using:
    https://<serverFQDN>:8443/upgrade/status

 

Additional reboot

Due to a kernel upgrade, an additional reboot is performed when you upgrade. It may take longer than expected for MobileIron Core to become available on the network.

 

Upgrade impact on Windows devices

In some cases, when an administrator initiates Reset PIN for a Windows Phone 10 device, the device does not return a new pin for that device.

For more information, see the following knowledge base article: https://help.mobileiron.com/s/article-detail-page?Id=kA134000000QxnLCAS

 

Ports

HTTPS/ port 443 is the default port for fresh installations, but upgraded environments keep the previous port open, for example, port 8080.

Check disk space availability

Before you upgrade, check disk space availability. At least 35 MB of disk space must be available in the /boot folder for an upgrade to be successful.

If at least 35 MB of disk space is not available in the /boot folder, contact MobileIron Technical Support before proceeding with the upgrade.

Use one of the following methods to check disk space availability:

The CLI command: show system disk

The following sample output shows the available disk space in the last line. It is 15M in this example.

CORE(8.5.0.1a-6)@host.company.com#show system disk

Filesystem Size Used Avail Use% Mounted on

/dev/sda3 181G 20G 153G 12% /

tmpfs 16G 4.0K 16G 1% /dev/shm

/dev/sda1 95M 76M 15M 84% /boot

The System Manager

The System Manager > Maintenance > System Storage menu shows you how much Core system storage you are using, and how much is still available.

Procedure 

  1. In the System Manager, go to Maintenance > System storage.
  2. Click More Details next to the System Storage bar that shows percent used.
  3. In this example, the available disk space is 190M.
