5.0 Upgrade Path

%UNIPLEX %TO informix-list@rmy.emory.edu %FROM rridley %SYSTEM DHLNET %SUBJECT 5.0 Upgrade Path %VERIFY y %DATE 02/12/92 10:22 %REFERENCE 7996 To all Happy Informixers out there! We currently have about 40 sites running Informix 4.0 Front-end and 4.1 Back-end (Both On-line and Standard Engine). Our problem is as follows : We can follow a 'gradual' upgrade path, eventually getting to 5.0 Front-and-back end, or we could go straight to 5.0. The way we see it our options are : 4.0 Front ____(A)____\\ 4.1 Front ___(B)____\\ 4.1 Front 4.1 Back / 4.1 Back / 5.0 Back | | | | | | |_______(D)__________\\ 5.0 Front /________(C)_____| / 5.0 Back \\ The questions we have are the following : Which steps require re-coding and/or re-compiling in order to be 'safe' ? What problems are we likely to encounter at each stage ? If we have to re-compile for stage A and/or C, then it would seem obvious that we may as well re-compile for stage D instead - is this true or are there some hidden implications ? A final question : We are currently running mostly on HP-UX 8.0 and 8.02 : Has anyone upgraded from 8.X to 9.X yet ? If so , how goes it ? Many thanks in advance, Richard Ridley %UEND
