For providing correct steps, please provide the screenshot of search topology in the search admin page (search admin page of search service application).

When two server farms share a search service application, there are at least a total of five search components in two server farms.

Here is an example for you. Remove a Search Query Component from WFE1, then add to WFE2.

1.Retrieve a list of search components.

$ssa = Get-SPEnterpriseSearchServiceApplication 
$active = Get-SPEnterpriseSearchTopology -SearchApplication $ssa -Active 
Get-SPEnterpriseSearchComponent -SearchTopology $active

Get the ComponentId of Search Query Component.

2.Clone the active search topology.

$ssa = Get-SPEnterpriseSearchServiceApplication
$active = Get-SPEnterpriseSearchTopology -SearchApplication $ssa -Active
$clone = New-SPEnterpriseSearchTopology -SearchApplication $ssa -Clone –SearchTopology $active

3.Add a new Search Query Component in WFE2.

$wfe = Get-SPEnterpriseSearchServiceInstance -Identity WFE2
New-SPEnterpriseSearchQueryProcessingComponent -SearchTopology $clone -SearchServiceInstance $wfe

4.Start the search instance in WFE2.

Start-SPEnterpriseSearchServiceInstance -Identity $wfe

5.Activate the cloned search topology.

Set-SPEnterpriseSearchTopology -Identity $clone

6.Clone the search topology again.

$ssa = Get-SPEnterpriseSearchServiceApplication
$active = Get-SPEnterpriseSearchTopology -SearchApplication $ssa -Active
$clone = New-SPEnterpriseSearchTopology -SearchApplication $ssa -Clone –SearchTopology $active

7.Remove the original Search Query Component in WFE1.

Remove-SPEnterpriseSearchComponent -Identity ComponentId of Search Query Component -SearchTopology $clone -confirm:$false

8.Activate the search topology again.

Set-SPEnterpriseSearchTopology -Identity $clone
