VMware did this because there are all sorts of really niche configuration options that almost no-one uses. History: vCenter and vSphere 6x are designed to be managed with your web browser, using flash.

– When you upgrade to vCenter or VMWare 6x, your vSphere Client (the program) will stop working! There is no client download on the website! How can you connect?

The vCenter install (particularly new installs) will bomb out if you don’t have good DNS. Make sure you can resolve it before you start the upgrade. Configure your DNS servers to have a fully-qualified name for vCenter (the old vCenter IP and your new vCenter’s name).Will be used for a few minutes during the upgrade. A ‘free’ IP address on the same subnet as your existing vCenter server.Make sure this matches the NTP source your hosts are using! This is a good time to standardize it across your environment. Network basics (internal domain name, subnet mask, gateway, two DNS servers).

Existing vCenter IP, verify root username and password (see next topic).Make sure to get the following configurations:

– Research before migrating or upgrading vCenter Make sure you have deep-dived into the existing vCenter appliance and each host before starting. Ideally, you have an Integrated Lights-Out (iLO) module on your servers, which will allow you to restart them or power on/off remotely. Make sure you have a plan for what to do if a host doesn’t come back after rebooting. You can perform this entire process (vCenter and ESX host upgrades) 100% remotely. – Can I upgrade vCenter and vSphere remotely? But in that case, you should have a team of experts on the job, so you shouldn’t need much help from this lowly blogger. If you have 100+ hosts, then your odds of a server randomly crashing during the upgrade gets closer to 5%. What are the odds a host crashes in that 2-4 hour period? Generally extremely low (less than 0.1%) unless you have more than 5 hosts.

DRS, HA and vMotion will not be available, so you won’t have normal redundancy.Īs long as you complete your upgrade in a reasonable amount of time (one evening), you should be fine. Remember that the hosts will keep running the VMs, the storage, and the virtual networking unchanged even if they can’t reach vCenter. Just don’t plan to do other management tasks at the same time. Good news: For small and medium businesses, there is almost no chance of customer impact while upgrading vCenter. – What is the risk of downtime while upgrading vCenter? If something goes wrong at this stage, remember you can shut down (power off) the new vCenter and then start your old vCenter and it should recover.ĭon’t forget the preliminary research, system checks, and preparation is another 4 hours for a small or medium business (this includes research for vSphere upgrades).ġ-2 hours of the preparation is getting the images downloaded, either to your burned DVD or directly from the VMWare website. VMWare is very good about this process and will perform many system checks before shutting down your original vCenter. Figure one hour to deploy the appliance (no risk, original vCenter is unchanged), then another hour and a half to replace your existing appliance (your original vCenter is shut down). – How long does it take to upgrade vCenter?Ībout 2-4 hours during the actual upgrade process.

Check my other blog with step-by-step instructions for upgrading from vCenter appliance 6.0 (or 6.5) to 6.7. You will need to upgrade to 6.0 or 6.5 first, then perform the jump to 6.7. You can’t upgrade directly from 5.5 to 6.7. – Upgrade from 5.5 to 6.7 cannot be performed in one stepįirst, heads-up.

Fix: Conflicting VIBs error (HP servers especially).

Problem: Can’t migrate vCenter after upgrade due to CPU compatibility.

Fix: CPU Generation Compatibility Levels (read this BEFORE upgrading).
