When upgrading from vSphere 6.5 to 7.0, there are certain conditions that could potentially cause conflicts or outages to virtual machines (VMs). The two conditions that could cause such issues are:
A. The use of a Windows vCenter Server system B. Datastores attached to the hosts based on VMFS3
Here is a more detailed explanation of why these conditions could cause issues during the upgrade:
A. The use of a Windows vCenter Server system: In vSphere 7.0, VMware has moved away from the Windows-based vCenter Server system and is now offering only the vCenter Server Appliance (VCSA). This means that if an administrator is currently using a Windows-based vCenter Server system, they will need to migrate to the VCSA before upgrading to vSphere 7.0. If they don't, it could cause potential conflicts or outages to the virtual machines (VMs).
B. Datastores attached to the hosts based on VMFS3: VMFS3 is an older version of VMware's file system for virtual machines. In vSphere 7.0, VMware has removed support for VMFS3. If an administrator has datastores attached to the hosts based on VMFS3, they will need to migrate the data to a newer version of VMFS (VMFS5 or VMFS6) before upgrading to vSphere 7.0. If they don't, it could cause potential conflicts or outages to the virtual machines (VMs).
C. The upgrade of a vSphere Distributed Switch with VMs attached: This answer is not correct as vSphere Distributed Switch upgrade with VMs attached should not cause potential conflicts or outages to virtual machines. However, the upgrade process should be performed with caution and according to the proper VMware guidelines.
D. The upgrade of an external platform services controller: This answer is also not correct as upgrading the external platform services controller should not cause potential conflicts or outages to virtual machines. However, the upgrade process should be performed with caution and according to the proper VMware guidelines.
E. The use of third-party custom vSphere Installation Bundles (VIBs) installed on the ESXi hosts: This answer is also correct as third-party custom vSphere Installation Bundles (VIBs) installed on the ESXi hosts may not be compatible with vSphere 7.0. It is recommended to check for compatibility before upgrading to vSphere 7.0, and to remove any incompatible VIBs before the upgrade. If incompatible VIBs are not removed, it could cause potential conflicts or outages to the virtual machines (VMs).
In summary, the two conditions that could cause potential conflicts or outages to the virtual machines (VMs) when upgrading to vSphere 7.0 are the use of a Windows vCenter Server system and datastores attached to the hosts based on VMFS3.
