Migrating User and Password Objects between Active Directory Forests

Windows, ,

As part of some internal lab work, I had to move the user objects with their passwords to a new forest. It was key to migrate the passwords to ensure that disruption to the users was minimized.

To migrate the users, I used the Microsoft Active Direction Migration Tool (ADMT + documentation) alongside the Password Migration Service.

migrate users between forests overview

In this blog post I am going to cover;

  • Create connectivity between both AD Forests
  • Installing the ADMT software + Password Migration Service
  • Creating a user list for migration
  • Migrating User objects + Passwords between AD Forests

Create connectivity between both AD Forests

There must be IP network connectivity between the DC’s in your Forests.

DNS setup

You need to configure conditional forwarders between your forests, so they can resolve one another.

On the source domain controller;

  1. Open up the DNS console, and right click the Conditional Forwarder folder to create a new record.
  2. Enter your target domain name and IP address/es of your domain controllers in the target domain. Select “store this conditional forwarder in active directory”, to replicate to other DCs in the source domain.

VMware LifeCycle Manager – Migration error “SSH is not enabled or invalid” – LCMMIGRATION15102

VMware, , , ,

During my migration from vRSLCM 2.1 patch 2 to the latest version 8 release, I encountered the following error;

Error Code: LCMMIGRATION15102

vRSLCM Migration Failed with SSH is not enabled or Root credential invalid. Please make sure SSH is enabled or porvide the correct root credential by adding the credential to the home page locker app

Pretty obvious error, however the provided root credentials were correct, and I could use putty to connect to my existing LCM instance.

Migration Process

The best news about this release is the “easy installer“, which also allows you to migrate from older versions. In this post, I’ve documented the screenshots in steps for you, as I know many of you out there like to see the end to end process before you undergo an update yourself, so you know what to expect.

During this migration process the following will happen;

  1. New LCM virtual appliance deployed
  2. New IDM appliance deployed (unless you select to link to an existing environment)
  3. Existing LCM settings and content will be migrated

Upgrading VMware vSphere 5.5 to vSphere 6.5 (VMUG Presentation)

VMware, , , , , , , , , ,
Blog post born from a VMUG Presentation

Mid Feb, one of the London VMUG leaders posted on twitter, looking for someone to present on the subject of “upgrading from vSphere 5.5 to vSphere 6.5”.

So I jumped at the chance, kind of, and offered to present. This blog post covers the content from that presentation.

  • vSphere 5.5 – End of Support
  • vSphere 6.5 – New features
  • OK, so let’s just upgrade then?
  • The plugin’s
  • SSO is gone!
  • Understand your topologies
  • Pre-Upgrade Tasks
  • The Upgrade, the big event
  • Gotcha’s
  • VSAN Considerations
  • vShield Manager is no more! Upgrade to NSX Manager
  • Resources

The presentation is available to download here – http://vexpert.me/London-vmug-dean (case sensitive link)

Or I’ve figured out how to embed it from Slideshare.net below (But animations don’t seem to work);

vSphere 5.5 – End of Support
  • End of General Support for vSphere 5.5 is September 19, 2018
    • Includes vCenter 5.5, ESXi 5.5, VSAN 5.5
    • KB 51491
  • In the event you are unable to upgrade before the End of General Support (EOGS) and are active on Support and Subscription, you have the option to purchase extended support in one year increments for up to two years beyond the EOGS date.
    • Expect this to be more costly than general support.
    • SLA’s are more akin to that of basic support rather than production support
    • Annual security patch. Includes catastrophic/critical security fixes only
    • Ability to create hot patches for Severity 1 issues only
  • Technical Guidance for vSphere 5.5 is available until September 19, 2020 primarily through the self-help portal.
  • During the Technical Guidance phase, VMware does not offer new hardware support, server/client/guest OS updates, new security patches or bug fixes unless otherwise noted.
    • For example, there was no SPECTRE/Meltdown security patches released for vSphere 5.1

It’s not only the core vSphere 5.5 products that are affected, as we can see from the End-of-Support tracking page provided by virten.net. There are other VMware solutions that you have deployed that may also need upgrading.
