(3)administrators group on the server on which you are running the PowerShell cmdlets
2.Stop search service by using PowerShell.

$ssa = Get-SPEnterpriseSearchServiceApplication -Identity <SearchServiceApplicationName>

Migrate only content databases. Go through your security & permission settings. Create new search service application, topology according to your existing settings to reduce database size and improve overall performance.
