Can this be done in a single step?

Yes, you can go from 5.2 ro 6 with no issues. Here is a matrix for your review.

According to the official release notes for code 6.0.196:

5.2.157.0 or later 5.2 release

You can upgrade directly to 6.0.196.0.

However there are some notes that you MUST read that are really important:

Example:

In controller software release 5.2 or later, the  WLAN override feature has been removed from both the controller GUI and  CLI. If your controller is configured for WLAN override and you upgrade  to controller software release 6.0.196.0, the controller deletes the  WLAN configuration and broadcasts all WLANs. You can specify that only  certain WLANs be transmitted by configuring access point groups. Each  access point advertises only the enabled WLANs that belong to its access  point group. Access point groups do not enable WLANs to be transmitted  on per radio interface of AP.

Do not install the 6.0.196.0 controller software  file and the 5.2.157.0 ER.aes boot software file at the same time.  Install one file and reboot the controller; then install the other file  and reboot the controller.
