Upgrading From Previous Versions

To upgrade from a previous version of the Web3 platform, simply run the installer as normal, following the prompts as described in the previous sections. The installer will reinstall the Windows services and the Web3 site so it is possible to change the user accounts assigned to run these services as part of the upgrade process if desired.

After installation, there may be some additional steps required to complete the upgrade of existing data. These are described below.

Upgrading from a Previous Version

After upgrade of the Web3 Platform, you must resynchronize all topic maps to their schemas. To perform this resynchronization, first install or upgrade the Web3 Admin tools and then launch Windows PowerShell and add the Web3Admin PowerShell snap-in with the following command:

Add-PSSnapIn web3admin

Then for each topic map you must synchronize its schema by issuing the following command, replacing {tmaddress} with the full URL used to access the topic map (e.g. http://localhost/web3/topicmaps/578c4b5b-b671-41f8-b7d4-7dbb6748eba1).

Sync-TopicMap {tmaddress} -Follow

Please also note that after the upgrade your browser may still have cached pages and scripts that can make it appear that you have encountered a problem with the service or that the upgrade has not been successful. Clearing the browser cache or forcing a page refresh (typically ctrl-F5 or ctrl-R) will fix these issues.
