If a database 10.2.4 is installed on Redhat Linux 4. Now there is a requirement to migrate to Redhat Linux 5. Now If we install the oracle home on Linux5 and take a cold backup from Redhat Linux 4 and if suppose the directory structure is absolutely same. Then after just restoring from the cold backup (datafile, redolog file, controlfile) everything. Will trying to just startup the database will work.
