I have to migrate one database. I have exact server replica. (Same directory structure on target as well as source database) Previously i have performed DB migration using export/import datapump (As we dont have access to any tools). I want to ask : Whether i can create replica using Cold backup method ? DB Details : Oracle 10.2.0.3 (On Both Source & target) DB is currently running in no archive mode. Steps i am going to follow : 1) `create pfile from spfile` 2) `shutdown normal` on source db 3) Copy `pfile` to target server `$ORACLE_HOME/dbs` 4) Copy all the `dbf` , `ctl` , `rdo` files to target server (Using binary mode FTP) (`select name from v$datafile; select member from v$logfile; select name from v$controlfile`) 5) `startup pfile='<path>'` on target server Doubts : Can cold backup can be used to create replica/ DB migration ? If i tried above process , shall i am able to start the db on target server without any errors ? As i don't have any archive logs , will that create any problem here ?
