Best Practice for migration from EM 5.2.1 R2 to Sophos Central cloud solution?


I am embarking on migrating all of my windows 7 & 10 clients from Enterprise Manager to Sophos central cloud solution.

So far I have found the installation of the new web client problematic and have had to remove the old client first which is not very convenient.

Is there a guide to the best way to address this migration or does anyone have first hand experience that can offer me advice?

Thanks for any help or advice.
