tx luc ,

right now there is no direct wat to upgrade to core 7 from powershell version2.

can we choose to uninstall version 2 and go for clean install for 7 .

will this work without any other prerequistes .

[LucD]

The lowest supported version is PSv3, so you'll have to make it a 2-step process.

You have options:

- upgrade PSv2 to PSv5.1 and then upgrade to PSv7

- uninstall PSv2 then install PSv7

uninstall PSv2 then install PSv7  this is what iam also thinking .

however just checked some article wherein powershell 7 coexists with 5.1 .

but as yu mentioned its not possible  with version2 correct??

[LucD]

PSv2 was deprecated with the Windows 10 upgrade in Fall 2017.

So you should definitely update that to PSV5.1.

If you want to use a side-by-side setup, you can install PSv7 as an MSI package.

Don't forget to make sure to have the correct .NET version!

Hi Luc

thanks just thought of summarizing again to following steps .if yu can please validate.

side by side install on windows 2008 R2 along with version 2.

1:dont touch version 2.0

2:Install the Universal C Runtime on Windows versions predating Windows 10. It's available via direct download or Windows Update.

3:Install the Windows Management Framework (WMF) 4.0 or newer on Windows 7 and Windows Server 2008 R2.

4:

Download the installer package

The MSI file looks like PowerShell-<version>-win-<os-arch>.msi. For example:

• PowerShell-7.0.0-win-x64.msi

[LucD]

Are you planning to keep PSv2 and PSv7 side-by-side?

You do know that PSv2 is not supported anymore.
Moreover, the PowerShell Extension in Visual Studio Code does not support PSv2 either.

so below is fine for clean install of 7?? i want to make it simple to have powershell core 7 on windows 2008 r2.

1:uninstall windows powershell version 2.0

2:Install the Universal C Runtime on Windows versions predating Windows 10. It's available via direct download or Windows Update.

3:Install the Windows Management Framework (WMF) 4.0 or newer on Windows 7 and Windows Server 2008 R2.

4:

Download the installer package

The MSI file looks like PowerShell-<version>-win-<os-arch>.msi. For example:

• PowerShell-7.0.0-win-x64.msi

[LucD]

Yes, that should be fine for a side-by-side installation.
But there is no documentation for doing this with PSv2, since it is not supported anymore.

Do at your own risk!

[jvm2016]

i am sorry to ask this but we are uninstalling version 2 before going for version 7 so it shud not be called side by side installation.

[LucD]

I was still looking at the version where it said "dont touch version 2.0"

Does that mean you will only have PSv7 and no PSv5.*on the side?

[jvm2016]

uninstall version 2 completely and then do fresh installation of 7 .is this not possible.

[jvm2016]

yes no ps 5.* 

[LucD]

Yes, uninstall PSv2 and then install PSv7 should work.

Note, not every module out there will work with PSv7.
VMware PowerCLI will only work with PSv7 partially.

[jvm2016]

well in that case what whould be the rirght approach sothat powercli works fine .

will it be below

first upgrade to powershell 5.1 .

and then install powershell core 7 .

[LucD · Accepted solution]

Unfortunately PowerCLI only supports all modules in PSv5.1.

In PSv7 some modules are not supported.

I use a side-by-side install PSv5.1 + PSv7 to cope with all cases.
