There is several things to consider before moving. I have migrated 2 snap based systems into epic pr-1. (one with 10 brains eb2 and one R1 and the other with 6 brains eb2 and a R2)
Setting the external PAC’s in the PR-1 IS pretty simple. Assuming you have your EPIC setup already it is very important to do firmware and software updates prior to try the PR-1.
NOTE: do not start the epic if you have a SNAP-PAC controller in the system running a strategy live, both controllers will drive your i/o points crazy)
I did this steps based on the pac’s i was working with:
1-Make backups before than anything, zip them so files can’t be opened by accident by pac control or display. save copies with reference to the software version, ex. pacv95July719.zip
2-Download and save latest firmware for all snap i/o units you have. Opto ftp.
3-Update units firmware, restart.
4-Test if system is working (still in old version of pac etc.) if so, then…
5-Update PAC soft. to version 10 plus, open the control and display files, they will be updated to the version, check tags, etc and check if everything works so far, it will ask you to debug because the v10 file in the PC is modified from any 9.x version in the controller, do so, and test if so far all is ok then backup this new version of your strategy and display, name it again with reference to the version as zip. ex. pacv10-2aJuly719.zip
6-If everything works, ASSUMING you have a rack controller actually running, then the controller have to be set to I/O processor only, remove autorun flag and the strategy from it, eliminate the loopback IP and set the controller basically as brain (this is different if you have stand alone controller, if so, just power it off for now, several possible scenarios if you plan to use it as backup unit) (You can use pac manager to delete the strategy from old pac and change IP if needed)
7-In PAC control v10 add the new controller (PR1) and remove the old from the controllers list, save, debud, open display and find new controller, auto correct tags and regenerate I/O. check if everything works.
8-Backup new project again but add reference to new controller ex. pacv10-2aJuly719EPIC.zip
I may have missed something here, but it will be good to have a migration guide, I think the 3 more important things here are “FIRMWARE updates” “stopping/removing strategy from old CONTROLLER” and “PAC software update” DO NOT TRY EPIC IN PAC DISPLAY UNDER VERSION 10, several errors and will mess up your current file, hence the need of prior, mid and after backups.
