As far as I know, ALTER TABLE ALTER COLUMN does not drop the indexes,
you will have to drop them manually.
I would not expect there any tool to be available for anything of this
large scale. Doing it for once database is not that difficult: script the
indexes, drop them, create the ALTER TABLE commands, and run the index
scripts. But of course doing this 150 times manually, is error-prone.
It could be worth the investment to look into using DMO for the task.
This is probably the best bet, as I believe DMO includes scripting
functions. (I have never used DMO myself, though.)
