The below processes are for SQL Express and Full SQL only, and are not relevant to SQL CE.Before any actions are taken, SkySync Files should be backed up to a folder on the desktop to prevent loss of connections and configurationsC:\Program Files (x86)\SkySync\appSettings.configC:\Program Files (x86)\SkySync\connections.configC:\ProgramData\PortalArchitects\Data\KeysAdditionally all jobs in SkySync should be paused toTo prevent discrepancies between the SQL Serversandthe SkySync Service will need to be stopped on every node accessing the SQL database. If any programs are in place that automatically start the SkySync service they will need to be disabledas well. All activity on the SQL database should also be avoided until the migration is complete to prevent database discrepancies. |

The process of transferring the SQL database will depend on your individual setup. The setups below assume that you are using the same SQL login ID's after the transfer as you where before. Ifyou arethis is notusing the same login ID's then their ability to connect to SQL should be tested prior to beginning the process. This is because SkySync will not be able to be re-installed if they cannot connect. |
Scenario 1: SQL and SkySync are located on the same server and need to be moved to a new server
In this scenario SkySync and the SQL Database are located on the same Server or Virtual Machine, and need to be moved to a new server. A common reason for this would be a system upgrade. To do this the SQL database will need to be moved, and SkySync will also need to be reinstalled on the new server with a custom install. Additionally the Keys folder located at C:\ProgramData\PortalArchitects\Data\ will also need to be moved from the old server to the new one. The processes below go over Moving SQL and reinstalling SkySync and should be followed as necessary.
Scenario 2: SQL and SkySync are installed on two separate Servers and only SQL needs to be moved

the case SkySync will need to be reinstalled to utilize the new logins. |
Moving SQL to a different server
The recommended method of moving the SQL databases is to perform a backup on the Source Database and a restore on the Destination database. Before this is done the SkySync service should be stopped to prevent additional information being written on the old database. Also any other programs that access the SQL database should be stopped while the migration is occurring.
1) Stop the SkySync Service on every node accessing the SQL database. If there are any programs which automatically start stopped services they will need to be disabled
2) Stop activities that access the SQL Database
3) Backup the SQL database and move it to the new server
4) Restore the SQL database on the new server

Scenario 3: SQL and SkySync are installed on two separate Servers and only SkySync needs to be moved
This scenario is most common a upgrade is occurring resulting in SkySync needing to be reinstalled on a new server/node. As with anytime a migration of any type is taking place it is important to stop activity on the database and pause all SkySync jobs as well as stop the SkySync service. It is also necessary to move a copy of the Keys folder located at C:\ProgramData\PortalArchitects\Data\ to the new server. After this is done simply reinstall SkySync using the most recent installer on the new server being sure to use the custom install so that the SQL server can be specified. Once SkySync has been reinstalled copy the keys folder into the path C:\ProgramData\PortalArchitects\Data overwriting the folder that will have been created automatically.

Scenario 1: SQL and SkySync are located on the same server and need to be moved to a new server
In this scenario SkySync and the SQL Database are located on the same Server or Virtual Machine, and need to be moved to a new server. To do this the SQL database will need to be moved, and SkySync will also need to be reinstalled on the new server with a custom install. Follow the processes above first for moving a SQL Database and then for Reinstalling SkySync.
Scenario 2: SQL and SkySync are installed on two separate Servers and only SQL needs to be moved
When the SQL server is being upgraded and it is located on a separate server from SkySync then it is not necessary to move the SkySync installation. As with any scenario the SkySync service should be stopped, and actions effecting the SQL database should be halted. After SQL has been moved simply edit the connections.config file located in C:\Program Files (x86)\SkySync to reflect the new SQL server name and restart the SkySync service. Follow the process above for Moving SQL to a different server.

As mentioned above if the SQL login user ID is changed SkySync will need to be uninstalled and reinstalled in order to connect to the new SQL database. |
