[TouchPad Development] synchron50:
So I decided to go from CM10 (4.12) to CM 11 (4.42) using the default partition sizes from JC's Toolbox, however, i just did an A6 refresh, followed by an 'Install Android' as I decided to keep WebOS for this 1st attempt. Not knowing what to expect since most folk are wiping WebOS with 'Complete Data Reset' as recommended, I backed up most of my SD Card to the PC as well as a Titanium backup. Using a Win7PC system, here is my experience using the tool:

1) Running the BAT script, couldn't find my novacom drivers. I had to do my own path command and rerun the script (possibly since I ran the BAT file on another partition other than C??).

2) I selected 2 recoveries (TWRP and new CWM GUI), latest 4/9/14 JC CM11 ROM and 4.4Gapps, script aborted due to it seeing the 2 recoveries. I thought the /boot could handle 2 recoveries as it did previously.

3) Reran the script and removed the CWM. No problems with any partitions during the check.

4) Observed that using the defaults and resizing the existing partition took around 35 to 40 minutes. I'm assuming this is the legacy media partition called SDCard1 in CM11.

5) Rest of the script went fine, it rebooted, installed latest JC CM11 with 4,4 Gapps and I got to a new 4.42 screen. Noticed an SDCard partition (data/media) with around 10G free and an SDCard1 partition with 610M free.

6) Rebooted into WebOS, everything was fine except it would have several warnings about freeing space due to the 600M free.

7) Rebooted into new TWRP 2.7. It points to the new sdcard which has no TWRP backups on it. I then wanted to use my backups from my PC but, alas, no matter what I tried to do it wouldn't effectively mount the touchpad for my PC to see it for USB file transfer. I rebooted into CM11 and copied a TWRP backup (data only) from SDCard1 legacy to SDCard where there was a TWRP folder with nothing in it.

8) Back to TWRP, go figure, I still could not find the files in SDCard. After scratching my head I finally managed to find how to point to SDCard1 and find the CM10 TWRP backup I wanted. I made sure to check Data only and Clicked Restore. This whole TWRP thing from step 7 took over an hour.

9) Rebooted back into CM11 noting the long time it took to "upgrade/optimize" close to 200 apps.

10) I finally saw my Wallpaper and PIN lock screen and was able to get to logon ok which leads me to....

11) CM11 Issues due to restoring my CM10.0 /data:

a) Trebuchet launcher kept FCing constantly making the TP useless - at 1st I thought it was older CM10 gapps conflict and reinstalled 4.4 gapps but that didn't help. I found a newer CM11 trebuchet and installed that but that didn't help. Finally, I had to clear data/cache in settings and that fixed the FC's. However, more importantly, the home screen and 5 pages of widgets and shortcuts were all lost. It remembered my Wifi connection, location, accounts but I had to re pair all my Bluetooth devices. GPS Map data was lost and had to be redownloaded.

b) Seemingly all apps remembered their settings but apps that would rely on media would misbehave since everything expected to be on SDCard would be on SDCard1. On some games I had to move some stuff from SDCard1\Android\data to SDCard\Android\data in orderto play.

c) Apps requiring SU permissions would initially need to ask for it so something with SuperUser must have changed in CM11.

d) Several apps had to be upgraded.

e) even with A6 refreshed, I'm getting -20 to -24 current draw during sleep<Correction, I did another A6 refresh via Toolbox and now I'm getting -6 to -8>.

I guess my main concern with running the Toolbox like this is the fact that I now have 6.66 storage on SDCard and 3.23G on SDCard1 and a questionable 350M or so on the SDCard1\Android\data which, I'm not sure if that can be deleted or not. I think that if you choose this option to keep WebOS, some more space free should have been left on legacy so WebOS doesn't complain. BTW, is there a way for WebOS to see the new SDCard somehow? I moved most of my photos to the new SDCard which, for now, means WebOS can't access.

I've now configured Trebuchet/Widgets/apps to my liking and am ready to backup my first CM11 Nandroid. For the next attempt, I'd like to go back to my CM10 jc Apr 2013 build using toolbox and restore my CM10 backup, then try it again the recommended way and get rid of WebOS. Will I be able to reverse the process and go back to one Android SDCard (the current one that is called legacy SDCard1?

Kudos to JC for some excellent development work as I really didn't want to migrate to KK until something like this came out and CM11 was a little more stable.
