[ATTENTION] Be careful with Copy-SPSite and Colligo!

Analysis of Copy-SPSite and Colligo

Folks be careful when using Colligo in your organization, careful with Copy-SPSite. Otherwise you may end-up with several issues regarding Colligo is unable to sync some sites:
According to the description provided by Microsoft Copy-SPSite:

Use the Copy-SPSite cmdlet to make a copy of a site collection from an implied source content database to a specified destination content database.The copy of the site collection has a new URL and a new SiteID. When you have database snapshot capabilities on a computer running SQL Server, a temporary snapshot of the source database is created for the duration of the copy to prevent any data changes during the copy process. If you do not have database snapshot capabilities on the server running SQL Server, you can back up the source and restore it to the destination to get the same result.

Copy-SPSite is creating a new site with new URL and a new SiteID, but the WebID is the same. The WebId of the original site and cloned one are the same. Yes that is true the WebID stay the same and this is what is confused for Colligo. Because Colligo relays on WebID as unique identifier.

How to get that? Here are the steps:

1. Find out which is the "Storage Location" for Colligo Briefcase. Go to View->Options
2. Go to this location, you will see "Sites.db" file:

3. Open the file with "DB Browser for SQL Lite", but first close Colligo and open Webs table.
Under Server Name is the WebID of the site and if you go to SharePoint server you will see it is the same GUID provided by Get-SPWeb. You can compare both WebID's of the sites, original ones and the one created with Copy-SPSite ... they are the same. Of course the logic that is used by Colligo is not allowing you to synchronize sites created with Copy-SPSite.

Interesting is that OneDrive for Business does not have this problem and synchronization is working fine. Why? Because Microsoft use a different logic for unique identifier. Normally the OneDrive for Business local cache access database is located here: C:\Users\Pavlov Aleksandar\AppData\Local\Microsoft\Office\15.0\OfficeFileCache\CentralTable.accdb. Open the DB in Access and than open MasterFile table.


As you can see the logic used by Microsoft for storing the information about the site is OneDrive for Business is GUID/relative path, in this case STID${CB935F8C-1D73-4BEC-B54E-D2E23D013CDC}/sites/loadtest22.

At the beginning to me it was also too strange to believe that WebID of two or more sites could be the same and in my opinion Microsoft changed this logic a while ago. But this may be a huge problem for companies using Colligo for file synchronization between SharePoint and local PC if somebody from Colligo do not pay attention to this problem.

Hope you will find this post helpful.

If so please share it.
