we have four 48000 directors, at level 5.3.0, and need to upgrade them.
The question is if we can upgrade directly to the latest version (6.4.0c) if we disable all ports.
We know that it is not recommended, but we do not need it to be a "warm" upgrade.
Thanks in advance.

--->>> The question is if we can upgrade directly to the latest version (6.4.0c)
No, directl upgrade from 5.3.x to 6.4.x is not allowed and not supported.
The procedure is 5.3 -> 6.0.x -> 6.1.x -> 6.2.x -> 6.3.x and finally -> 6.4.x
for details refer the Release notes, or here in the community you can find 100 of Threads about Upgrade procedure.
