Brocade 6510 at v7.1.0a and need to get to v8.2, whats the path and are there several hops of code? Are there expected issues getting to the final version?
is a commmon question, see follow Thread
You need follow this path: (non-disruptively)
- 7.1.0a to 7.2.x
- 7.2.x to 7.3.x
- 7.3.x to 7.4.x
- 7.4.x to 8.0.x
- 8.0.x to 8.1.x
Before you upgrade, please read release note v7.x.x, v8.x.x (in this document you can see,migration Path, switch support,etc), because if your switch is connect to another switch(fabric) you need know the Fabric OS Compatibility.
