If you utilize hosts files instead of a valid forward and reverse dns entry then this one my rear its ugly head during your migration. There is a workaround with two parts. You really should use the first part of the workaround and skip the second part which continues the use of hosts files. This is why you are in this mess in the first place. Please check it out.
As usual VMware magnanimously offers to provide extended support for a ‘small’ purchase price.
“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. Visit VMware Extended Support for more information.”
If support is just a best-case scenario and you can stomach going it alone (with Google searching) then Technical Guidance with be available for another year until September 19, 2020.
“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 more information, visit VMware Lifecycle Support Phases.”
Technical Support is always a good option to have and for all of you knowledge seekers it is a great way to learn the nuances of VMware products. See my previous post Tech Support is Not a Dirty Word for my take.
Sooner or later you will have an occasion to call VMware tech support in your career as a VMware admin. If you’re anything like me you want to figure things out for yourself but not take too long. You don’t want to admit you don’t know the answer but logically how can you know all the answers all of the time. Over the past 6 months my co-worker and I have been in this very situation more than a few times with our VMware environment. What I have learned is to be more humble and maybe a little quicker in making that support call. In every case I have learned so much from support that I feel like I received free VMware training. As much as you can learn from reading a technical book and researching a knowledge base article it just pales in the face of real world experience. Don’t be afraid to quickly assess your ability solve a technical problem in a timely manner versus calling support. You will gain experience by working with those more experienced than you that tackle these problems on a daily basis.
