Synchronizing cDOT Cron Schedules Cluster to Cluster

The following tool can be used to synchronize cron schedules from one Clustered Data ONTAP cluster to another (even if they are on a different ONTAP version.)

The tool can be run in a variety of ways. The example below is run from simply double clicking a BAT file - no prompts need to be answered:

The Script - Sync-Cron.ps1

## To run in a BAT file (switches optional):

# Powershell.exe .\Sync-Cron.ps1

## To create $SecurePasswordString run:

# PS> (Read-Host -AsSecureString) | ConvertFrom-SecureString

# N.B. This string only works when logged in as the same Windows user that created it.
