AIX 5.2 to 5.3 migration
Hello All,
We want to upgrade our 44p Model 270 from AIX 5.2 to 5.3. This is a standalone devlopment server but downtime is something we don't want because we have a short development deadline looming. I have no tape drive to make backups to. I myself am a developer and don't have any particular AIX experience, although I do have a fair amount of current experience with HPUX and Solaris.
My questions are:
- Is this just an update or a full blown OS instal?
- Will my existing apps like clarify and oracle 9 still be on the machine or will I have to reinstal them?
- I have read threads saying to make 2 system backups to tape. I do not have a tape drive but might have a cdr on the machine, can i back it up to that?
- Is this easy enough and does the software provide enough guidance that a person of my skill level could expect to accomplish this successfully
- About how long should i expect and effort like this to take assuming there are no serious problems?
Thanks,
Fred

NAME
tcopy - copy a magnetic tape
SYNOPSIS
tcopy source [destination]
DESCRIPTION
The tcopy utility copies the magnetic tape mounted on the tape drive specified by the source argument. The only assumption made about the
contents of a tape is that there are two tape marks at the end.
When only a source drive is specified, tcopy scans the tape, and displays information about the sizes of records and tape files. If a des-
tination is specified, tcopy makes a copies the source tape onto the destination tape, with blocking preserved. As it copies, tcopy pro-
duces the same output as it does when only scanning a tape.
The tcopy utility requires the use of Berkeley-compatible device names. For example,
example% tcopy /dev/rmt/1b /dev/rmt/2b
