Function Copy-SqlServerAgent
{
<#
.SYNOPSIS
Copies *all* ProxyAccounts, JobSchedule, SharedSchedules, AlertSystem, JobCategories,
OperatorCategories AlertCategories, Alerts, TargetServerGroups, TargetServers,
Operators, Jobs, Mail and general SQL Agent settings from one SQL Server Agent
to another. $sourceserver and $destserver are SMO server objects.
 
Ignores -force: does not drop and recreate.
 
.DESCRIPTION
This function could use some refining, as *all* job objects are copied.
 
THIS CODE IS PROVIDED "AS IS", WITH NO WARRANTIES.
 
.PARAMETER Source
Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2000 or greater.
 
.PARAMETER Destination
Destination Sql Server. You must have sysadmin access and server version must be SQL Server version 2000 or greater.
 
.PARAMETER SourceSqlCredential
Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use:
 
$scred = Get-Credential, then pass $scred object to the -SourceSqlCredential parameter.
 
Windows Authentication will be used if DestinationSqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials.
To connect as a different Windows user, run PowerShell as that user.
 
.PARAMETER DestinationSqlCredential
Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use:
 
$dcred = Get-Credential, then pass this $dcred to the -DestinationSqlCredential parameter.
 
Windows Authentication will be used if DestinationSqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials.
To connect as a different Windows user, run PowerShell as that user.
 
.PARAMETER DisableJobsOnDestination
When this flag is set, copy all jobs as Enabled=0
 
.PARAMETER WhatIf
Shows what would happen if the command were to run. No actions are actually performed.
 
.PARAMETER Confirm
Prompts you for confirmation before executing any changing operations within the command.
 
.PARAMETER Force
Drops and recreates the objects if it exists
 
.PARAMETER DisableJobsOnSource
Disables the jobs on source

.EXAMPLE
Copy-SqlServerAgent -Source sqlserver2014a -Destination sqlcluster
 
Copies all job server objects from sqlserver2014a to sqlcluster, using Windows credentials. If job objects with the same name exist on sqlcluster, they will be skipped.
 
.EXAMPLE
Copy-SqlServerAgent -Source sqlserver2014a -Destination sqlcluster -SourceSqlCredential $cred
 
Copies all job objects from sqlserver2014a to sqlcluster, using SQL credentials for sqlserver2014a and Windows credentials for sqlcluster.
 
.EXAMPLE
Copy-SqlServerTrigger -Source sqlserver2014a -Destination sqlcluster -WhatIf
 
Shows what would happen if the command were executed.
