Be aware that from release 3.7.0 of MX, internal code changes have made MX less tolerant of log files that are not perfectly formated; therefore it is harder to [[Moving_from_Cumulus_1_to_MX#Considerations_when_moving_between_Cumulus_flavours|move log files between the Cumulus flavours]]. |

| == Moving files from Cumulus 1 to MX==
| |
|
| |
| *Steve Loft designed MX so that in general it was able to read [[Moving_from_Cumulus_1_to_MX#Log_files|log files]] created by the original Cumulus.
| |
| *See individual articles for more details on such differences.
| |
| *'''Please note, the information for MX is taken from notes by Steve Loft, and applies to MX 3.0.0. Although, some updates have been made in line with release announcements by Mark, it is likely Mark has made other changes that affect the various log files that are not detailed in the release announcements, possibly making some content obsolete.'''
| |
|
| |
| In particular '''internal''' changes mentioned in release announcements for versions 3.6.x, and 3.7.0, have made MX work significantly differently.
| |
| * If you move from Cumulus 1 to a version of MX up to 3.5.y, the transfer is likely to be significantly easier. This is because Steve Loft was keen to keep forward compatibility.
| |
| ** Cumulus 1 is tolerant of various separators for dates and times. Cumulus MX 3.0.0 insists all times use a colon separator (says Steve Loft), and all dates are in ISO format.
| |
| **However, MX 3.0.0 will read the date/time entries in the Cumulus 1 format, and it will only change them to the new format when it needs to update a particular entry (e.g. an extreme) in that particular file. Consequently some files will have a different formats for the extremes that have existed for a while and for any new ones, meaning both formats will co-exist in those files.
| |
| * If you move from Cumulus 1 to a version of MX that is 3.6.z or higher, you may find that log files can no longer be read.
| |
| **In particular 3.7.0 onwards releases are very fussy about symbols used to separate parts of dates, within times, and all must match the latest locale settings.
| |
|
| |
| General points:
| |
| * Note that if you run MX on a UNIX based operating system (e.g. Linux or Raspberry Pi OS) all file names are case-sensitive, please read documentation to see where capital letters are required in those file names. Be aware that wiki pages change first letter to a capital even when a file that must be all lower-case is being described.
| |
| * Cumulus 1 is reasonably tolerant of numbers using a comma to separate the integer and decimal part of real number.
| |
| ** MX 3.0.0 will accept both decimal commas and decimal full stops in the standard log files, the extra sensor log files, and the daily summary log file.
| |
| **In all versions of MX, the software expects periods/full stops in .ini files regardless of the locale in use, please see the [https://cumulus.hosiene.co.uk/viewtopic.php?f=27&t=12908 Cumulus MX Announcements and Download - PLEASE READ FIRST] for details, but generally if you want to transfer these files from Cumulus 1 to MX, it is best if '''you edit them so all decimal numbers have a "." between the integer and decimal parts'''.
| |
| * In individual articles, any differences in the precise content or format within individual files will be highlighted.

| ==Moving Files from MX to Cumulus 1==
| |
|
| |
| When Steve Loft designed his original Cumulus (1), he had no experience to draw upon as to the best way to treat items like dates. When he designed Cumulus MX, he was able to learn from his experiences with both Cumulus 1 and Cumulus 2, and he decided to use dates to an ISO specification (ISO 8601 Data elements and interchange formats – Information interchange – Representation of dates and times), and therefore log files are not [https://cumulus.hosiene.co.uk/viewtopic.php?f=4&t=15167 backwards compatible].
| |
|
| |
| That said, there are some features in Cumulus 1 that are [[Moving_from_Cumulus_1_to_MX#Cumulus_1_features_not_ever_going_to_be_included_in_MX|missing in MX]], and there are Cumulus users who have migrated back either on a temporary basis (to use a missing feature before they return to MX) or in a very few cases decided to stay with Cumulus 1 (because they prefer it).
