Before we start on a new request, please tell us if any of our suggestions did what you wanted before this last set of changes so we have some idea as to whether or not we have finally correctly interpreted what you're asking us to do.
Then please clarify your requirements:
Do you want only the files with names matching sasmm_fsbc_durds_id000[0-9]*_t?*.dat.trnsfr.gz to be renamed, or do you want every file matching id000[0-9]*_t to be renamed?
Do you want the file names to restart at 7111 in each directory processed, or do you want files in all of the directories processed to be treated as a single list numbered starting at 7111 and incrementing for each file processed?
Do you have a backup of this directory hierarchy in case something goes horribly wrong during the renaming process?
Are you absolutely sure that no file existing before this renaming process begins has a name that will match any new file name that will be created by this renaming process?
When you say you want these changes applied to files for dates:
is that range inclusive or exclusive? (I'm assuming you want files in 2011/03/01 renamed, but it isn't at all clear whether you want files in 2012/03/26 renamed.)

device_rename
DEVICE_RENAME(9) Device drivers infrastructure DEVICE_RENAME(9)NAME
device_rename - renames a device
SYNOPSIS
int device_rename(struct device * dev, const char * new_name);
ARGUMENTS
dev
the pointer to the struct device to be renamed
new_name
the new name of the device
DESCRIPTION
It is the responsibility of the caller to provide mutual exclusion between two different calls of device_rename on the same device to
ensure that new_name is valid and won't conflict with other devices.
NOTE
Don't call this function. Currently, the networking layer calls this function, but that will change. The following text from Kay Sievers
offers
SOME INSIGHT
Renaming devices is racy at many levels, symlinks and other stuff are not replaced atomically, and you get a "move" uevent, but it's not
easy to connect the event to the old and new device. Device nodes are not renamed at all, there isn't even support for that in the kernel
now.
In the meantime, during renaming, your target name might be taken by another driver, creating conflicts. Or the old name is taken directly
after you renamed it -- then you get events for the same DEVPATH, before you even see the "move" event. It's just a mess, and nothing new
should ever rely on kernel device renaming. Besides that, it's not even implemented now for other things than (driver-core wise very
simple) network devices.
We are currently about to change network renaming in udev to completely disallow renaming of devices in the same namespace as the kernel
uses, because we can't solve the problems properly, that arise with swapping names of multiple interfaces without races. Means, renaming of
eth[0-9]* will only be allowed to some other name than eth[0-9]*, for the aforementioned reasons.
Make up a "real" name in the driver before you register anything, or add some other attributes for userspace to find the device, or use
udev to add symlinks -- but never rename kernel devices later, it's a complete mess. We don't even want to get into that and try to
implement the missing pieces in the core. We really have other pieces to fix in the driver core mess. :)
