Upgrade from 9.1 to 9.2

Hi, I would like to know if any major changes need to be carried over from 9.1 to 9.2 version upgrade. As we had some changes performed when we moved from 8.5.1 version to 9.1.0:

• Winscp to SSH.net
• Marketplace solutions to be upgraded to latest versions also Navigation center replaced applications reports, security audit reports. so, we had to remove the existing AR, SAR solutions.
• We had .vb in the extension wherever the xfbr has been referenced that extensions were no longer supported in 9 version.

Thanks in Advance!
