Secure store service issue in SharePoint 2013

Recently were trying some tests on migration of SharePoint 2010 contents to SharePoint 2016 , having SharePoint 2013 as intermediary server without which the migration will not be successful .

Had this weird issue of Secure store service application not being created in SharePoint 2013, the farm was built by someone a yr ago , so did not have the full data on the issue , but below were the errors in ULS

Microsoft.SharePoint.SPException: Your session has expired. Restart this wizard to continue.  

 at Microsoft.SharePoint.Administration.SPScenarioContext.GetContext(Page page, CultureInfo culture)   

 at Microsoft.Office.SharePoint.ClientExtensions.SecureStoreAdministration.CreateSSSApplicationStateInfo.OnLoad(EventArgs e) 

Application error when access /_admin/sssvc/createsssvcapplicationstateinfo.aspx, Error=Your session has expired. Restart this wizard to continue. 

The current state '_admin/sssvc/createsssvcapplication.aspx' doesn't match the Page '_admin/sssvc/createsssvcapplicationstateinfo.aspx'

I was unable to fix this issue not the root cause of it yet , but figured it out that this was an issue only through the UI , so I could still go ahead the create a new Secure store service application through power shell 

New-SPSecureStoreServiceApplication -ApplicationPool "app pool name which already exists" -AuditingEnabled:$false -DatabaseServer "devomasp02" -DatabaseName "Secure store SANew"-Name "Secure store SANew"

$secureStoreApplicationName  ="Secure Store Service Application"

Get-SPServiceApplication | ? {$_.GetType().Equals([Microsoft.Office.SecureStoreService.Server.SecureStoreServiceApplication])} | New-SPSecureStoreServiceApplicationProxy -Name $secureStoreApplicationProxyName -DefaultProxyGroup | Out-Null

I shall look into issue and keep posted if I fix it
