Hey Karl,

thank you very much 4your quick answere. Thanks!

I will try it tomorrow and give an feedback if that helps.

but I must not use the flag  /fi to copy the shares?

Thanks!

You want to use ShareDUP to copy the share themselves from the old server to the VNX5300 VDM.  Here's the syntax of the ShareDUP command:

Usage: SHAREDUP \\source \\target srcdrive

           [/LU] [/ND:domain_name] [/IP4700] [/PREFIX]

          [/FO[+]:outputFile|/FI:inputFile][/LOG[+]:logFile]

Where:

\\source               Netbios name of the source server.

\\target               Netbios name of the target server.

srcdrive               Drive letter of the server source to select for the

                        duplication (example C:). Specify "ALL", to select all

                        drives of the source server.

So, in my case, "CRCNAS02" is an old Windows 2003 server and "CRCNAS02-tmp" is the CIFS server on my VG2.  I used the following command at the command line:

X:\SHAREDUP \\CRCNAS02 \\CRCNAS02-temp ALL /LU /LOG+:SHAREDUP.txt

and I get the following written into the logfile called "SHAREDUP.txt"

SHAREDUP 02.03

Source server:DFDNAS02        5.0

SHAREDUP

\\dfdnas02

\\dfdnas02-tmp

ALL

/LOG+:SHAREDUP.txt

Creating share "\\DFDNAS02-TMP\asa01collections$"

to export directory "C:\fs_ev02collections\data"...

-> OK

Now, on my VG2, I have a hidden share (note the "$" indicates a hidden share) on my new VG2 for the filesystem.  All the output was appended to the LOG file (note the "+" indicates append to log file, not overwrite), which I can review for errors.

You can also use the flag /FO: to write out all the shares to a text file.  At a later time, you can use /FI: to read back in that same file and create the shares, based on the entries in the text file.

Let us know if that helps!

The /FI flag stands for "File Input".  It tells SHAREDUP to read in the Share from the text file you supplied and write it to the destination CIFS server.  In my example above, I copied the permissions directly from the source Windows server to the destination CIFS server without writing to a file - only the output was logged to my file, not the share listing. 

If you want to write out the share permissions to a file, you must use SHAREDUP with the /FO flag to write the share permissions to your file in one step.  Then, you must run SHAREDUP with the /FI flag to read in from your text file and write to the destination CIFS server.  Does that make sense?

Thanks!

Hi Karl,

at first i have to say thank you 4 your help!

I hope you can help me one more time. I got the callange:

I have to migrate 3 old fileserver to 2 new vnx cifsserver.

The old fileserver: File-Server#1 M1S02 (some files for employees)

                          File-Server#2 M1S21 (Outlook-Archive, Profiles)

                          File-Server#3 M1S08 (Install; Backups)

These fileservers has to be migrate to CIFS01 and CIFS02.

My question ist: What are the correct paramater when i use lgdup to copy the local groups?

                           What are the correct parameter for emcopy to copy all files correct to the new fileserver?

                            When i use sharedup to copy the share to the new cifs server, which parameters should i use? The                             same as you post?

Iam sorry for beeing a newbie at this theme. I hope you can tell me, what is best practice in this case?

If you got any question, feel free to ask me!

THANK YOU!

Greetz Riccardo

I agree that reading the docs and understanding the options is better than just copy&paste commands without know whether or not they are the best choice for your particular environment

to re-iterate what Karl mentioned, if this is your first migration to this platform you can setup a test CIFS server or practice with a virtual appliance

https://support.emc.com/docu10716_VNX_for_File_Simulator_Installation_and_Configuration_Guide.pdf?language=en_US

No worries, Riccardo - the included README.txt files with each has shows each flag for each command.  I strongly urge you to try each command out and understand how the flags affect each command.  You must understand what happens if you include/remove certain flags.  If you blindly run commands - mine or anyone else's here - you run the risk of failing to copy shares, groups or ACL information and be forced to do all the work all over again.

My suggestion for the process is:

0) TEST, TEST and TEST until you understand the entire process and your fallback options

1) copy local groups with LGDUP and review the logs

2) copy shares with SHAREDUP and review the logs

3) copy files with EMCOPY and review the logs

For LGDUP, your commands might look like LGDUP -L+ \\SOURCE \\DESTINATION:

LGDUP -s -v -l+ M1S02-CIFS01-LGDUP.txt \\M1S02 \\CIFS01 (note the direction and number of backslashes)

This would copy any local groups to the destination and attempt to merge any local groups found, but not set any local groups members in case of an error.  Why would I do this instead of another flag?  I leave that as an exercise for you to figure out.

For SHAREDUP, if you wanted to write out your shares to a file, your commands might look like SHAREDUP \\SOURCE \\DESTINATION /FO: /LOG+:

SHAREDUP \\M1S02 \\CIFS01 ALL /SD /FO:LSL-NAS01-SHAREDUP.SHR /LOG+:LSL-NAS01-SHAREDUP.txt

For EMCOPY, you want to understand your flags before you use the command.  One possible string might look like:

EMCOPY \\M1S02 \\CIFS01 /O /A /S /SD /C /R:3 /W:2 /SDD /STREAM /LOG:C:\M1S02-CIFS01-EMCOPY.txt /PRESERVESIDh

I can't say strongly enough that you need to test this with a subset of your data, then check your permissions and ACLs.  It will greatly simply things.  Thanks!

It's not required to run SHAREDUP before EMCOPY, but it's the most common practice.  Thanks!

Hi Community, Hi Karl,

thank you very much for all response by you! That was very helpfull! Again Thank you very much! I studied the emc pdf.

The vnx simulator is a great stuff! Thanks to dynamox!

I will try to migrate the data.

I got only one question left. I have to execute the sharedup before the emcopy data migration? Is that rigth?

Thank you very much@all
