clearcase.
Please help.

Re: [cciug] SVN to Clearcase migration

This is the accepted answer.
This is the accepted answer.
There is a open source program called svn2cc that works pretty well. You can download it at http://svn2cc.sarovar.org. If you choose to use this tool, a couple things I would recommend are:
1. Clean out your svn repository. Primarily make sure no file names contain a '$' as it will cause the load to fail due to a regex parsing error.
2. When dumping your svn repository (the svn2cc uses a svn dump file), keep the dump to small blocks of revisions incrementally. I kept the blocks 100 revs or less. This will make recovering from any errors much easier. The first dump I did not add the incremental flag too.
Example dumps:
svnadmin dump -r 0:100 > dump-1-100.dmp
svnadmin dump -r 101:200 --incremental > dump-101-200.dmp
3. Create a dedicated CC stream for the import process.
4. Create a dedicated CC label for the import process.
There are two flavors the tool comes in. One creates a series of batch files that need to be executed after java program is run. The second makes CC call directly from the java program. I used the latter of the two. I did make two changes to the code. The first was to cleanly handle the regex problem in point 1 above (requires java 5 or above). The other was to output the results of the CC commands because the error messages normally output by the program are not very helpful...
Good luck with the transition! -

Thanks for your reply. I have gone through the webpage provided by you. It seems that svn2cc utility is to convert SVN dumps to cleacase commands but my requirement is that I need to convert all the source code reside in the SVN repository to clearcase repository.- SystemAdmin

Do you have a particular question?
Thanks for your reply. I need step by step procedure to move all the source code from SVN to clearcase. I have never done this ever before.

The utility does exactly what you need. It does it in one two ways. The fist is to create a series of batch files that need to be executed after the utility runs. The batch files, when executed, will then insert the source files into CC. The second is to directly insert the records into CC from the utility. You can choose what option is best for you project.- SystemAdmin

The SVN dump file contains all the data you need. That includes the source file and its associated meta-data (history, author, etc). Your SVN administrator will be able to generate the dump files for you.
If you don't need to preserve all the meta-data, update your SVN view to the most current. Copy the files to your CC view. From the CC view add the files to source control. Using this method will treat each file as new file and all history will be lost.

I want to use that option where history, metadata can be maintained.
I have downloaded three utilities svn2cc, cc_direct, svndump. Can you please tell me what is the significance of cc_direct and svndump utility.
I have following setup.
SVN server is on windows
Clearcase server is on windows
Can you please tell which option I should use in all these utilities to create the svndump file and export all the source code to clearcase with an example.
Please help.

The svn2cc_direct jar file contains the source and binaries for direct inserts into CC (no batch files).
The SVNDump I have not looked at, unfortunately, I do not know what that does.
To dump svn you need to use the svnadmin dump command. svnadmin should have been installed when subversion was installed. I used svn on linux so I am not sure where the subversion windows install places that file.
Example svn dump commands. For more information see the Subversion Documentation.
This command will dump the entire repository, from my experience, I would not recommend it.
svnadmin dump path/to/repository > full_repo.dmp
This command will do a full dump the first 100 versions of the svn repository - Recommended
svnadmin dump path/to/repository -r0:100 > full_r0-100.dmp
This command will do an incremental dump versions 101-200 of svn repository - Recommended. Repeat this command until all versions of repository are dumped.
svnadmin dump path/to/repository -r101:200 --incremental > incremental_r101-200.dmp
Then to load into CC. See the svn2cc documentation for switch meanings and any additional switch you man need. You should make an label type in CC before importing. See CC mklbtype man page for details (cleartool man mklbtype).
Repeat below command for each dump file created during the dumping process. I used the direct calls so, I only needed to use the below statement.
java -Xmx512 -jar <path/and/Name of jar file> <path/to/dump file> -t "" -c "cleartool mklabel -replace " -v -

Thanks again for your reply but frankly speaking I did not understand anything.
Could you please give me step by step procedure as I am very new to SVN. I have worked on CC for last 7 yrs. But SVN is really new to me. Actually the requirement is that one of my project is using SVN to maintain the source code and now company want to migrate from SVN to cc.
Environment is as follows
SVN server : windows
CC server : windows
Please Please help

Also I was looking at the svn dump command and flags and some of the other commands. Do you know if it is possible to dump by a date range and not just by revision. I do not see this in the documentation for dump. Of course I am still going through it, but thought you might know better from your experience.

I'm fairly familiar with svnadmin, but not an "Expert". I can confidently say that there is no such way to dump a range of revisions based upon some date criteria you pass as argument(s) to svnadmin. If you think about it, since all revisions in svn are chronological, it shouldn't be too difficult to find the desired revision number(s) and dump accordingly. Now, if you are trying to dump only certain revisions (many of them) that were only committed on certain dates (many of them), then you have an entirely different issue and you should think of another way to solve the problem, IMO.- SystemAdmin

But like I said, finding commit dates for each revision is easy so essentially just pick which revisions you want and tell svnadmin dump those revision numbers.
Also might give a look at the command svndumpfilter. -
