Process Permissions on FIle Servers

Hi All

I have not been involved in a migration for the past 3 years. Now we are migrating between forests for users/groups, workstations and email. Which is all good.

We have a question around the File Server Migration process and whether it can be streamlined? I am looking to find out

1. Can we run an initial Vmover command and start to process permissions. Even if all users and groups are not migrated? And then run a delta to permission new folders and also add missing users and groups?

2. On data this is dedupe'd - Does this have any effect when running VMover?

Thanks

Thanks for the replies. So more stats around the file servers - in prep for the Vmover taks. Is there any loose formula or ball park figure that can be used to say, re-permission around 100,000 files?

I guess that there are many factors, but a ball park figure would be ideal.

Is it all on the item count or does file sizes become a factor?

Thanks

File sizes don't matter - whether a file is big or small, it only has one ACL. It's all about the number of files and folders.

I am glad it is purely file items. From experience, do you have any idea to say if there are x number of files then it will take around x hours to complete the process?

Thanks

X per hour depends on the host being processed. It is also files and folder for this count of X. I have seen it in the 1M and 100K ranges. Again it is all about the hosts.

Again to elaborate on Jeff's point - it's the classic "it depends, so benchmark in your environment" situation.

Influencing factors:

Processor speed

Disk responsiveness

General VM tuning (if file server host is a VM)

Loading of physical VM host server (again, if your servers are virtual)

PS I did some checking on stats from my last project and we saw processing speeds in the range of 300 to 500K files / hour. Your mileage may vary.
