Let's imagine I have created an Azure virtual machine, a small one initially. I have installed SQL Server and created databases. Also hosted to website by IIS on the virtual machine. I can see the performance of the small one is not up to the mark. I want to upgrade to a larger machine more powerful one. I know, I can do this from Azure portal.
I have already fully configured this machine with databases and websites running on the small VM. I need to know if I lose all my data and hosted websites if I change size of Virtual Machine (VM) from Small to large from Azure portal? I am worried that if this upgrade I may lose data and website.

Its should not affect your data. Because your VHD is stored in a blob, which is completely separate from the Virtual Machine resources running the OS within the VHD
