TFS 2015.1 upgrade/migration error [End of Central Directory record could not be found]

Hi there,

Few days ago I had a opportunity to upgrade/migrate production TFS 2013 Update 3 to TFS 2015 Update 1. The migration process is “straightforward” but as usual every time something goes wrong. Unfortunately, this time I didn’t have exception Smile.
As I mentioned above, we had TFS 2013.3 but it wasn’t a clean installation, that was an in-place upgrade from TFS 2008 –-> 2010 –> 2013 in the last couple of years. This time I decided to do upgrade to the new hardware.

Here I’ll not explain how to migrate, I want to explain what type of error I had and how solve problem.

During the upgrade process I got error and warning…
[2016-02-15 20:13:22Z][Error] End of Central Directory record could not be found.
[2016-02-15 20:13:19Z][Warning] Invalid zip file in process template MSF Agile For Project Server 2007, End of Central Directory record could not be found.
[2016-02-15 20:13:20Z][Warning] Invalid zip file in process template MSF CMMI For Project Server 2007, End of Central Directory record could not be found.

When you try to find resolution on the Internet you will find NOTHING! But luckily error is obvious. We need to delete problematic Process Templates. Open Process Template Manager from the Visual Studio, find the problematic templates and delete them.

When you are done, have to repeat whole procedure. Backup databases, restore, upgrade… and at the end you will have successful TFS upgrade Winking smile

Thank you Ognjen for your precious help Smile

Cheers

Datacenter on Laptop [VM with Routing and Remote Access Server]–Part II

Hi there,

As promised in my previous post, here I’ll show you how to install and configure Remote Access role in one Virtual Machine on laptop. Why do we need router between Laptop and virtual machines? For virtual machines in lab environment I need isolated network segment, different from other networks, my production network, home network etc. but the most important thing is because I don’t want to switch virtual network adapters (wired and wireless), on every virtual machine every time when I am on a different network. For example; when I’m at the Office have been using wired network, when I’m at home have been using wi-fi, when I’m speaker at conferences have been using mixed network connections. In this case I need switch virtual network adapters only on one virtual machine (“Router”).

As you can see here I have three virtual network adapters created. The first is RomeLabInt for all virtual machines inside Lab network. The second is WiFivLan which I have been using on WiFi network and the third is WiredvLanv when I have been using on wired network.

Next step in this configuration is installation of “Router” virtual machine. OS is WS2016 TP4. Virtual machine has two virtual network adapters, one External and one Internal. Internal adapter has a fixed IP address, in my case this is network subnet 10.10.20.0/8, Router’s IP is 10.10.20.1 and other virtual machines will be use that IP address as a default gateway. External adapter has IP assigned by local DHCP.

Now we are ready to install Remote Access role on Router virtual machine what’s simple as that. Only what you need is to follow pictures below Smile.

Remote Access role is installed and now we need to configure RRAS. Follow the pictures again.

We are done with RRAS and now can access to outside world from Internal network and from the our Hyper-V virtualized hosts as well.

The network stack is set up and now we can go further. The next step in this scenario is installation of Active Directory and will be installed on virtual machine in one of Hyper-V virtualized hosts.
In the previous post I explained how to enable nested virtualization on Hyper-V virtual machine and already have VM installed as well as I have VM promoted as a primary domain controller. Domain controller is the DNS and DHCP server.

image

So, what’s the next step? In the next post we will see how to prepare Active Directory domain, how to setup Organizational Units with security groups, how to add Hyper-V hosts in that group, how to prepare virtualized Hyper-V hosts and whole infrastructure for the High Availability etc.

Until then, stay tuned Smile

Cheers,

Romeo
