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 don't 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 ?
