Upgrade Question

I will be upgrading 12 databases on our development box next weekend. If things work out this will be followed by the production box.

Because of the time factor, I will install the 8.1.7 to a new ORACLE_HOME and upgrade the databases over the weeks after so that there will be both 8.1.6 and 8.1.7 databases on the same box.

My question are:

1. During the install of 8.1.7 do I install a new listerner
2. Can I have two net8 configuration on the box.
3. After I have upgrade all of the databases, can the 8.1.6 software be de-installed
4. Which ORACLE_HOME takes precedent
5. I will use the Oracle Database Migration Assistant. If anyone has used this, how long will it take to migrate say a 10g database.
6. Can anyone body suggest any thing I have missed out or should watch out for

I have read all the oracle8i migration doc. and the 8.1.7 install doc. but wish to hear from those who have done it for real

Thanks in advance

I would run one listener and let it listen for both $OH's. You should use the latest; 8.1.7 in your case.

neither. You ORACLE_HOME is your ORACLE_HOME.

Depends. On a decent box, probably about 20 mintues.

Looks like you got it pretty well covered. I like to take a cold backup before I migrate the db. That way, if something dies in the middle of the migration you can restore your 8.1.6 and re-migrate from the beginning.
