7MTT Multiple Job Parser

This might be handy for large 7 to C transition projects, to be able to get the outputs of all the 7MTT jobs (we’d mostly be interested in pre-checks) and line them all up side by side into one CSV (a column per job for comparison purposes), which makes it easy to filter on pre-check errors/warnings that either aren’t of interest, or are already known about, and then can focus on just the important stuff.

Its super simple to run on your 7MTT box, just do in PowerShell>

.\7MTT_Job_Parser.ps1

It automatically targets the 7MTT jobs folder. I added some other optional switches:

-FileOrFolder

-PrecheckFlag

-TransitionOp

-FileOut

The tool grabs all the .job files, converts them from JSON, and then generates a CSV. I’ve not currently implemented the “AREA” column (i.e. CIFS/NFS/SAN …), and the “Start Time” output could be improved.

An idea for the future would be to automate 7MTT session setup and running pre-checks - using 7MTT CLI - against any number of systems; then this tool can take the results of those pre-check jobs and parse them into one spreadsheet.
