I've performed searches and can't find an answer.
On my Windows system, I have a Qmgr personal Cert that will expire in 30 days. Our standards have changed and I must use a size of 2048 instead of the original requested size of 1024. Recreate request will ask for the incorrect size, of 1024, for the certificate.
When I try to generate an original request, using the size 2048, I get an errror that says the lable already exists in the database. This is True.
How do I get around this?
MQ V6.0.2.2
Windows 2003 R2
Thanks in Advance.

Create a new keystore. Generate the request there. Receive the certificate into that keystore.
Then either use the new keystore or export/import the new, larger, cert into the old keystore. |

Thanks Jeff.
Not "my" first choice but....if I choose to import the larger cert into the old keystore,once received into the new keystore, how much of a pain is that?
1. I can import it without a request being there?
2. What will happen to the old personal cert? Delete it first then import?
3. I take it there are no changes to be made if I stay with the same cypher, etc?
4. Basically, what process would you recommend?
Again, thanks for your help.

Is just importing the larger cert into the keystore enough? Don't you need to import as well the corresponding private key into the keystore?
I thought the signed cert contained only the public key?

There's a difference between "export/import" and "extract/recieve".

 I think I got confused for a minute there. Thanks for setting us all straight.

Life can be made easier by having an A and B key store. If A is the 'current' key store you generate a new certificate request in the B key store, receive the signed certificate, 'flip' the SSLKEYR attribute of the queue manager, and refresh security (SSL stylee). if it works, clear out the A key store ready for next year - if not, 'flip' it back to the A key store and sort the problem. Rinse and repeat...
Elegantly simple, and if you script it you can use a parameter file to feed in the values of key length, DN values etc., and cater for changes year on year.
