I was working with a client recently who had purchased Metalogix Migration Manager for SharePoint and I came across an issue that confused me for a minute. I installed the Metalogix SharePoint Extensions Web Services on a few farms. However, in the middle of this process a new version of the tool came out and I didn’t realize that some of the farms were running one version while the other farms were running a new version. I could connect to one farm just fine. However, when trying to connecting to the other farm (that had the newer version), I received a 404 error.
In my round of troubleshooting, I tried reinstalling and redeploying the solution package but to no avail. It wasn’t until I dug deep into the documentation that I realized that the version number was included in the path to the web service itself. It was then I realized that the version number of all web service extensions as well as the Migration Manager itself all have to be the same. If you are using this tool and run into a 404 error, be sure and check those version numbers.
Note: By writing this, I am not endorsing one particular SharePoint migration product over another. I work with all of them. It’s simply the tool being used on this migration. That means I don’t need any of Metalogix’s competitors calling or E-mailing me this afternoon. That means you Axceler and AvePoint. :)
