HI thanks for the tip with Irix 6.5.7, are you using 4.25 Legato on Irix
version 6.5.18 or any release higher than 6.5.7? If so are you experiencing
any issues, the reason I ask is we are going to move a 4.25 version of
Legato from Irix 6.5.3 to a new server running 6.5.18. We will have to load
legato from scratch and copy the NSR directories over, and hopefully all
the index's and databases will function.
If you have any insight into what problems could happen your input would be
greatly appreciated.
Thanks, and have a great day.
