Not sure about your comfort level with the CLI and SQL/Excel, but here's my thoughts:
1) Run this command from CLI: run sql SELECT name, description FROM device WHERE name LIKE "%VG224%" *** You'll need to updated the name info (where I have VG224) between the quote marks and the field is case sensitive.
2a) Copy the info into a spreadsheet and parse as needed using text to columns feature.
2b) Change the descriptions as needed.
2c) Create a formula that creates update SQL code.
Here's roughly what my spreadsheet looks like:
Cell A3 = AALN/S2/1@VG224.domain
Cell B3 = FoIP IN - 4457
Formula in C3 = ="run sql UPDATE device SET description="""&B3&""" WHERE name = """&A3&""""
(yes you really need that many quote symbols in there.)
3) paste updated SQL command back to the CLI.
Again not sure of the comfort level of the CLI. If you have butterflies I wouldn't recommend doing this as you could botch your system pretty easily... Also depending on your formatting this method of SQL updates may not work.
