Filr 4.3 upgrade halts with "The Update process has reported a warning or error"

When attempting to update the Filr Search server to version 4.3, the following message is presented:

The Update process has reported a warning or error. Review the returned text below:

Problem: product:Filr-4.3-0.x86_64 requires product(Filr) = 4.3-0, but this requirement cannot be provided
Solution 1:deinstallation of product:Filr-4.3-0.x86_64
Solution 2:do not install patch:Filr-4-2021-14-1.noarch
Solution 3:break product:Filr-4.3-0.x86_64 by ignoring some of its dependencies

The Micro Focus Filr team is looking into a solution. Until that time, the upgrade can be completed by following the instructions below.

• Ensure the Filr service is not running on any Filr nodes.
• rcfilr status
• Run this command on the Filr server to check the status.
• rcfilr stop
• Run this command on the Filr server to stop the service.
• At the Filr Search terminal, run this command:
• zypper rm open-vm-tools
• hit y to continue
• Paste this command into the Search server terminal session
  
• zypper dup --auto-agree-with-licenses --replacefiles --allow-vendor-change
• hit y to continue with each prompt
• After completed, reboot the Search Server
• Repeat these steps on other Search servers.
• Paste the following command into a terminal session for each Search Server:
• zypper in open-vm-tools
  
• Upgrade the Filr Nodes.

The Filr 4.3 upgrade has conflicts with some versions of VM Tools.
