6.5.1

Preparing for Upgrading the Content Library
When upgrading from vCenter Server version 6.0 or earlier, you must prepare your environment before
upgrading the Content Library to prevent pre-check errors.
If you are upgrading from vCenter Server version 6.0 or 5.5, your environment must meet upgrade
requirements for the Content Library:
n
All ESXi hosts from the source vCenter Server inventory must be supported by the destination
vCenter Server 6.5.
n
The source vCenter ServerContent Libraries must be backed by either Remote File System or
Datastores. You cannot use libraries backed by local file system of the vCenter Server.
n
All the remote file system shares used as library backings must be accessible at the time of the
upgrade.
n
No subscribed libraries are using file based subscription URI.
If you are upgrading from vCenter Server 6.0 Update 1, no actions are necessary.
If your environment does not meet the requirements, you must perform the following actions to prepare
for upgrade.
Verify Network Prerequisites Before Upgrading
Verify that your network is set up correctly and meets connectivity prerequisites for upgrading
vCenter Server.
For information on creating a PTR record, see the documentation for your vCenter Server host operating
system.
For information about configuring Active Directory, see the Microsoft Web site.
Domain users that are part of a Windows Administrators group with vCenter Server Administrator
permission cannot be used to authenticate vCenter Server during upgrade and do not have
vCenter Server permission after upgrade.
Procedure
1 Verify that the fully qualified domain name (FQDN) of the system where you will upgrade
vCenter Server is resolvable. To verify that the FQDN is resolvable, type
nslookup -nosearch -nodefname your_vCenter_Server_fqdn at a command-line prompt.
If the FQDN is resolvable, the nslookup command returns the IP and name of the domain controller
machine.
