PowerCLI script to change <ThreadStackSizeKB> in vpxa.cfg

[IgnitionUSMC]

I want to modify all of my 400+ esxi hosts with modified line in the vpxa.cfg file. I want to change the threadstacksizekb to 256 from 128

<Config>
<vmacore>
<threadPool>
<ThreadStackSizeKb>256</ThreadStackSizeKb>
</threadPool>
</vmacore>
</Config>

I usually use PCLI to do the majority of my tasks and this is no different. Help me PowerCLI community, you are my only hope 😜 /vStarwars

This is almost the same question as in Editing vpxa.cfg. Take a look at the answers provided there.

Ah, I figured it out... same way I scripted replacing the welcome & motd file.

#edit, cant get the script to display right
