Answer 1

Requirements to run scripts (powershell commands before you start):

Set-ExecutionPolicy Unrestricted  
  
Import-Module -name MicrosoftTeams  
  
Connect-MicrosoftTeams  

1) export all channels(private and public) from PowerShell of this team unifiedgroup1@Company portal .com.

Find your team name in Teams Admin or the display name that you see in Teams and edit the "YOUR TEAM NAME" part of the script.

$Result = @()  
#Get all teams  
$AllTeams= Get-Team -DisplayName "YOUR TEAM NAME"  
$TotalTeams = $AllTeams.Count  
$i = 0  
#Iterate teams one by one and get channels   
ForEach ($Team in $AllTeams)  
{  
$i++  
Write-Progress -Activity "Fetching channels from $($Team.Displayname)" -Status "$i out of $TotalTeams completed"  
Try  
{  
#Get channels  
$TeamChannels = Get-TeamChannel -GroupId $Team.GroupId  
   
#Iterate channels one by one and add to the result array  
ForEach ($Channel in $TeamChannels)  
{  
#Add channel info to the result array  
$Result += New-Object PSObject -property $([ordered]@{  
TeamName = $Team.DisplayName  
TeamVisibility = $Team.Visibility  
ChannelName = $Channel.DisplayName  
GroupId = $Team.GroupId  
ChannelId = $Team.ChannelId  
})  
   
}  
}  
Catch   
{  
Write-Host "Error occurred for $($Team.Displayname)" -f Yellow  
Write-Host $_ -f Red  
}  
}  
   
#Export the result to CSV file  
$Result | Export-CSV "C:\AllTeamChannels.CSV" -NoTypeInformation -Encoding UTF8

2) Create a private teams channel priv1 from PowerShell under the parent team unifiedgroup1@Company portal .com and make user1 as the owner.

New-TeamChannel -GroupId ObjectId -DisplayName "priv1" -MembershipType Private -Owner UserObjectID  

Find the ObjectId in Azure AD > Groups > Choose the group > Under Overview > Object ID

Find the UserObjectID in Azure AD > User > Choose user1 > Under Profile > Object ID

3) create a public teams channel pub1 from PowerShell under the parent team unifiedgroup1@Company portal .com and make user1 as the owner.

New-TeamChannel -GroupId ObjectId -DisplayName "pub1" -owner UserObjectId  

(see 2) for ObjectId and UserObjectId)
